`` I tried to build several desktop firmware and write it into ZC-328, but there is no content displayed on the HDMI connection monitor. With serial connection, information is displayed, but I can't input information in serial software such as PUTTY and XCOM. I thought it was my USB TO serial(PL2303TA) cable, so I bought a new one (CH340G), and it was still the same. The same is true for a ZC-328.Thank you!

Hi,

The ZC-328 board lacks a 100R resistor at the back position of the UART interface, as shown in the picture. This has resulted in the UART 2 RXD and the RK3288 CPU being effectively open circuit. An open circuit can be observed when measured with the resistance setting on a multimeter.

Please either short this spot directly to use the UART terminal normally, or add the missing 100R resistor.

Regarding the HDMI output, the boot log you provided is the init boot message, not the kernel log (which in fact would not confirm the problem either). Therefore, I cannot ascertain the issue, but you might control the system via UART after fixing the UART terminal and further investigate the issue.

I hope this helps!

[cntvro]

Are these two points? I tried to short circuit, but I still can't input information. Thank you!

[Angelic47]

Hi, yes short this spot directly and UART RXD (looks from RK3288 side, for PC side it sames as CH340_TX) would be connected. If still not, please check your soldering or wiring, or simply check if your wire was broken. Using a multimeter would helps you to troubleshoot what's going wrong, if necessarily.

Please notice: it's seems you get some obfuscated with GND and UART RXD. The pin from left to right is: GND, RXD, TXD, VCC. In your picture the TXD lines is actually connected with a black line. It's strange. I'm not sure if you are connected right or not.

DO NOT CONNECT VCC PIN TO CH340 OR YOUR BOARD WILL BE FRYED.

[cntvro]

I think my wiring should be correct, because there is no boot information displayed when it is connected incorrectly. I measured the wiring without short circuit with a multimeter.

[cntvro]

I tried again and again, and I succeeded. Thank you.

[Angelic47]

Glad to hear your success! 🎉 Could you please tell us the story that happend in past 30 minutes? I feel so interesting and want to know what causes you can't input anything to the uart terminal even you shorted the RXD resistor 😆

[cntvro]

I started using CH340, and I didn't know to short it. Later, I used PL2303TA again, but it still didn't work, because PA2303TA can be input but not confirmed. Until I saw you say CH340, I switched back to CH340, and I didn't expect to short it. Thank you very much. I'm sure I'll trouble you later. Are you from China?

[cntvro]

It's the first time to enter, it's memorable, thank you, haha.

Yes, absolutely, I can speak Chinese and I can understand what you say. The only reason that I'm using English now is making these contents being helpful for others who might have the same issue. Especially, for someone the native language is not Chinese.

Don't be worry, any language would be fine there.

---

是的，当然，我可以和你说中文，也能看得懂你的内容的。 唯一一个我继续使用英语的原因是这样会让这些内容对其他遇到同样问题的人来说更有帮助。 尤其是对于那些母语并不是中文的人来说更是这样。

不要担心，无论你选什么语言都是可以的呢。

[cntvro]

Ok, thank you. HDMI and Internet are still not working. Please see what the problem is. And the system will automatically restart every once in a while.谢谢！ kern.log.txt syslog.txt

[Angelic47]

Very glad to see you are in bash terminal now! 🎉 For the HDMI video, you might want to use dmesg to get the full kernel logs, or ls /dev to check if there has a framebuffer device fb0. And you may needs the panfrost driver to enable the GPU acceleration, which maximums the desktop performance for RK3288.

This can be very similar (even same) with other RK3288 series boards. Any other documentation for RK3288 boards can be referred.

Please forgive me for being a newbie, with only a little linux foundation! I will strengthen my study.

[Angelic47]

Regarding the automatic restart, here's what I know:

The board features an STC15 8051 microcontroller. Its P1.3 pin is connected to the reset pin of the RK808 power chip. Additionally, its UART is connected to UART3 of the RK3288, used for receiving commands from the RK3288.

Undoubtedly, this STC15 microcontroller implements a simple watchdog timer. If it is not periodically send the command to it, it will reset the power chip every ~5-10min, causing a complete power outage of the board. Moreover, the STC15 microcontroller also implements features such as timed power-on and infrared remote power control (as described in the original manufacturer's promotional materials).

Clearly, I have no clue on this, as I cannot access the firmware of this STC15 microcontroller using any non-invasive method. I also have no way to obtain the original manufacturer's ZC-328 firmware, as they keep it strictly confidential.

Therefore, I can only suggest the following two approaches:

1. Rewrite the firmware for the STC15 microcontroller. Pulling P1.3 to a low level will keep the RK808 power chip continuously operational;
2. Remove the STC15 microcontroller entirely, and solder the P1.3 pin to a low level.

---

关于全自动重启，这是我知道的：

这个板子上拥有一颗STC15的8051单片机。其P1.3引脚接到了RK808电源芯片的复位引脚。 另外，其UART接到了RK3288的UART3，用于接收来自RK3288的指令。

毫无疑问这个STC15单片机实现了一个简单的看门狗。 如果不去周期性发送命令喂它，那就会每隔大概5-10分钟就会复位电源芯片，产生整板断电。 此外，这个STC15单片机还实现了诸如定时开机，红外遥控开关机等功能（来源于原始的厂商宣传描述）。

很显然我对此没有任何头绪，因为我无法利用任何非侵入办法来获得这个STC15单片机的固件。 我也没任何途径获得原始厂商提供的ZC-328固件，因为他们对此严格保密。

所以，我只能提供如下两个思路：

1. 重写STC15单片机的固件。将P1.3拉至低电平，即可让RK808电源芯片一直工作；
2. 直接拆掉STC15单片机，并且将P1.3引脚焊接到低电平。

如果你的设备不能正常输出HDMI，则可以换一个屏幕和HDMI线缆再试一次。 据我所知屏幕分辨率不宜超过1920x1080，否则可能会出现问题。

如果反复尝试依旧无法成功，也许可能是缺少某些电阻导致的。 如果这样，你可以将整个板子拍照给我，我这里对照一下我的板子，看看是否有什么不同。

当然: 别担心，不需要多害怕什么。尽管放轻松把你遇到的问题提交就好。

If your device is unable to output through HDMI, you may want to try using a different screen and HDMI cable. As far as I know, the screen resolution should not exceed 1920x1080, as it may cause issues.

If you still face difficulties after multiple attempts, it might be due to missing resistors. If that's the case, you could take a photo of your entire board and send it to me. I can compare it with my board to see if there are any differences.

TIP: Don't worry, there's nothing to be afraid of. Just relax and go ahead to submit the issue you're encountering.

[cntvro]

Regarding the automatic restart： I asked the official to get the Android firmware, do you need it? In addition to the first point you mentioned, I don't think I can play it. The second point, if you give me a diagram, I think I can try it. I am very curious, ZC-328 this version of the whole network information is very little, the exchange of people are not many, such as you are still playing.

[cntvro]

[Angelic47]

As far as I know, the ZC-328 series have at least more than 5 versions, which could says "confusion". For every different version, the PCB can be straightly different.

The main different is the components that not soldered. And even more, some versions may have a little PCB design differents, but's not so critical.

The boards you are playing with now is most similar with mines, but still with some differents. Only way to confirm that there are no hardware related problems is compare it and see what's happend...

For the firmware, you can send it to me with my email admin#angelic47.com . (Please replace # to @) I will continue going deep when I have spare time.

[Angelic47]

By comparing, it's seems your board are somethings different than mine:

1. The USB 2.0 hub chip is missing. I'm not sure whether this would causes the USB ports (only side 4pin connectors) unuseable. If you are living in China, there does have a compatible chip provided by WCH, which can be directly replace and use. Or just buy the same chip and solder it to right position.
2. Seems there are some resistors missing near the RJ45 port. I don't know that acting as what functioning.
3. The STC15 8051 chip is sand-papered without any silkscreen. Well done, the manufactor really don't want you know their hardware using what chips.

The HDMI circuits seems fine. At lease I can't see there have any differents.

[cntvro]

I flashed the official Android firmware, and all the hardware on the board works normally, including HDMI and network. If there is no hardware, Android should be abnormal, right?

[Angelic47]

Yes, if the official Android firmware works fine, this might not the hardware related issue. It becomes more hard to address this issue...

According to your kernel logs, seems that kernel not detected the screen plugged-in. Maybe a hot-plugging detection problem?

I'm not sure, may give me some time and I will check the hot plug detection source codes from the RK3288 kernel.

[cntvro]

Thank you. If possible, can you help me solve the problem of network and automatic restart first? I don't need desktop at present, haha.

[Angelic47]

For some reasons, this may takes a long time to get the uart protocol with the STC15 microcontroller by reverse engineering.... I prefer to tell you, rewrite the firmware for the STC15 microcontroller, if you want's to use this boards as quick as possible 😆

[Angelic47]

Does the wlan (SDIO WiFI) not works either?

[cntvro]

There is no desktop, I will first study how to configure the network under the terminal. Good night, we can talk tomorrow.

[cntvro]

Does this show that there is something wrong with my network card driver? I didn't get the automatic IP after the system started. I tried to configure it, but it still didn't work. Using #nmgui also gives an error.Does this show that there is something wrong with my network card driver? I didn't get the automatic IP after the system started.

Hi, According to the all information you have provided, I believe that the hardware you are now using is straightly not compatible with mine.

First of all, the ethernet phy. I don't know what phy your board is using, but I am using the RTL8211E (In fact it's a compatible chip which manufactured by Chinese company). If the phy is not the same, the RJ45 port might not work. Even if the phy is the same, the reset pin of the phy might be connected to a different pin of the SoC. All of this will cause the ethernet port not working.

And then I found your SDIO wifi is not working either. Your SDIO wifi is straightly different from mine. The "Cdtech" is so strange that I have never heard of it. You might want to check which the real chip inside the module's shield.

By reviewing your kernel log, I found that the SDIO wifi is fully not recognized by the hardware. There missing the new high speed MMC card at address message for the wifi module. This means, the SDIO wifi module is not working entirely, even not powered on. Therefore, the reset pin of the wifi module might be connected to a different pin of the SoC.

This is a serious problem, if you can't find the correct pinout, and don't know what the phy and wifi module is, there could be no way to make them work.

For my board, I don't have the schematic either. I desoldered the SoC, and using a multimeter with the continuity test to find the correct pinout. This could be effective, if you have two boards or more. But it's dangerous if you only have one board. This could be saying "goodbye" to your board.

I hope this information could help you. Maybe you want to dump the android firmware, and decompile the device tree to find the correct pinout.

[Angelic47]

For some more information, you can refer to the following codes: ZC-328 kernel dts patch It's the line for the kernel dts patch for the ZC-328 board, which defines the RK_PB0 pin as the reset pin for the ethernet phy, with high level active. And the line 74 of the same file defines the RK_PD4 pin as the reset pin for the wifi module, with low level active.

These would be the examples of the reset pin configuration for the ethernet phy and wifi module on the ZC-328 board.

[cntvro]

Thank you, microcontroller, chip technology I know nothing about, if you are interested, I can send a ZC-328 board to the past, for you to study. Android original firmware, I sent you a few days ago through qq email.
