wr740n_v4 openwrt wlan can't work #100

Closed jacycle closed 8 years ago

jacycle commented 8 years ago

hello pepe2k, I have a board tplink-wr740n, I update the fireware openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-sysupgrade.bin when I build u-boot_mod and update, the logs are the following content.

The question is

  1. when I use u-boot_mod image, the wifi can't work, use the other boot, it works well. login the web, if channged the wifi configuration or led configuration will let the watchdog reset.
  2. The chip is ar9331, why the boot print SOC: AR9330 rev. 1

I don't down how to reslove the problem. Someone can give me a hand.

Hello @jacycle,

  1. The chip is ar9331, why the boot print SOC: AR9330 rev. 1

AR9331 == AR9330 rev. 1.

  1. when I use u-boot_mod image, the wifi can't work, use the other boot, it works well. login the web, if channged the wifi configuration or led configuration will let the watchdog reset.

First of all, I see at least two problems with your board:

  1. It seems that your MAC address is missing (MAC: 00:03:7F:09:0B:AD (fixed)). Did you combine old content of the second 64 KB sector with new version of my U-Boot modification image?
  2. The U-Boot sees DDR2 memory type on your board (RAM: 64 MB DDR2 16-bit CL3-4-4-10, DRAM: 64 MB DDR2 16-bit) which is definitely wrong as the WR740N supports only DDR1. That could be a hardware problem - memory type is recognized based on values of GPIO28 and GPIO12.

To be able to find the reason, I need more information from you:

  1. What exactly version of the OpenWrt you are using - is it official release or your custom build?
  2. Please, post whole two bootlogs.
  3. Please, issue in U-Boot command line md.l 0x180600ac 1 and post here output.

Piotr

hello pepe2k, I changed the spi flash to W25Q128FV, and I changed the ddr. My board is sendcond hand, The name of the board my be mistaken. As you said the mac address is missing, I write an address on 0x1fc00, the wifi works. but sometimes it will be reset by watchdog,

  1. the Openwrt is official release
  2. uboot> md.l 0x180600ac 1 180600AC: 0004220E ..".
  3. the following are the logs

Hello @jacycle,

First of all, your board reports DDR2 memory type and if it's TL-WR74x v4 for sure then you have some hardware problem on the board, with wrong GPIO bootstrap configuration.

Can you take a photo of your board or at least tell me memory chip mark/name? If the memory chip is not in BGA package then it's definitely not DDR2.

Please, try rebuild the code with defined CONFIG_BOARD_DRAM_TYPE_DDR1 (you can add it somewhere here: https://github.com/pepe2k/u-boot_mod/blob/master/u-boot/Makefile#L424). It will ignore bootstrap and setup memory as DDR1. Before you do this, make sure what type of memory you have on the board as it may not boot with DDR1 setup if there is DDR2 on board.

Plus, try to make some memory tests:

  1. Under U-Boot: mtest.
  2. Under OpenWrt: using memtester (should be available in OpenWrt repository, try opkg update; opkg install memtester; memtester 16 3.

Let me know about the results.

Hello @pepe2k I try another board, it works well and does not reset. There should be some hardware problems.

There's a ddr2 in my board, it's in BGA package.

Hello @jacycle,

It would be good to find the real reason of your problems. Please, make memory tests. The logs you showed is only about packages list update.

The new board, when I power down and power up, it will stop to print in somewhere at random and will make watchdog reset. If I enter the system, then for a while it will reset too. As before I said it works well, I first use the old boot and then update the u-boot_mod,

I maked some memory tests:

I'm sure the board gpios are as same as tplink_wr740n_v4 the reset gpio and the leds are working correctly when i use openwrt-ar71xx-generic-tl-wr740n-v4-squashfs-sysupgrade.bin.

Where is the code I can change the GPIO bootstrap configuration.

Hello @jacycle,

I will take a look on this problem. As I see, you are using OpenWrt BB version (kernel 3.10), am I right? Have you tried OpenWrt CC?

Where is the code I can change the GPIO bootstrap configuration.

If your board has DDR2 memory then your bootstrap configuration is correct. And it doesn't come from code - bootstrap configuration is read from some GPIO values at power up.

There is a chip of SiGe 2565T for the wifi. May be it's the problem.

I don't think so, this is just a PA.

jacycle commented 8 years ago

Hello @pepe2k,

There is a switch for wifi tx and rx There is a picture here http://pan.baidu.com/s/1eRSs6Ym

jacycle commented 8 years ago

Hello @pepe2k,

ar9331 A60(ANTC) A59(ANTB) to control the wifi tx and rx. Do I need to initialize in boot?

jacycle commented 8 years ago

Hello @pepe2k,

there is a signal for low to high and high to low in A60(ANTC) A59(ANTB). But u-boot_mod, always low level. Do you know how to configure the registers?

Basically, U-Boot doesn't touch WiFi at all (excluding reset it).

All WiFi related configuration should be done in the system/driver. Your board is custom one, so don't expect that regular OpenWrt image dedicated for TL-WR74xN v4 will work there and configure any external LNA/PA correctly.

IMHO, you should ask manufacturer how to configure external PA. It might be connected to some GPIO.

jacycle commented 8 years ago

Hello @pepe2k,

I just change the uboot, It works. the same firmware. I just want to know what is done in uboot, or what is the different.

Thank you anyway

pepe2k commented 8 years ago

Hello @jacycle,

I just change the uboot, It works. the same firmware. I just want to know what is done in uboot, or what is the different.

Changed to which one? And again, have you tried OpenWrt CC version?

Piotr

jacycle commented 8 years ago

Hello @pepe2k, I get the uboot from the board. (dd if=/dev/mtd0 of=/tmp/u-boot.bin). Then I changed the boot to u-boot_mod, after that, ANTB, ANTC is low level always, and someties wil trigger the watchdog. If I change back, There is high and low level in the pin of ANTB ANTC. I just changed the boot. Do you have the download address for OpenWrt CC version.

pepe2k commented 8 years ago

Hello @jacycle,

I get the uboot from the board. (dd if=/dev/mtd0 of=/tmp/u-boot.bin).

And how can I know what is done or not done in stock U-Boot code? I'm not a wizard... You haven't provided enough information about your board, ex. full stock bootlog.

Then I changed the boot to u-boot_mod, after that, ANTB, ANTC is low level always, and someties wil trigger the watchdog.

Is the only new code of my project not working on your board?

If you really want help and solve the problem, start to be more verbose please. "u-boot_mod" doesn't tell anything about the version, so next time write please something like "with last release 'Jun 19 2014' it's working, with new code from master branch, compiled using XYZ toolchain, it doesn't" etc.

Do you have the download address for OpenWrt CC version.

jacycle commented 8 years ago

Hello @pepe2k,

In the boot, I input uboot>setclk 6 Selected profile 6:

after reset, all works fine. I'm sorry about ANTB and ANTC, they are controlled by openwrt.

pepe2k commented 8 years ago

Hello @jacycle,

You are not answering my questions, so EOT from me.

Piotr

jacycle commented 8 years ago

Hello @pepe2k,

I forget to say that I also tried OpenWrt CC version, it’s as same as Barrier Breaker 14.07. CROSS_COMPILE=mips-openwrt-linux-uclibc- I'm sorry I didn't offer enough verbose. I'll try to do better next time.

thank you for you code, and thank you for the help.
