Hello! I've try to porting to the Allwinner F1C200s SoC device. I've successfully compile kernel module and load it on target system, but i can't see espsta0 interface in ifconfig -a output.

Kernel logs:

[   65.951657] esp32_spi: loading out-of-tree module taints kernel.
[   65.961218] esp_reset, ESP32: Triggering ESP reset.
[   66.178300] ESP32 peripheral is registered to SPI bus [1],chip select [0], SPI Clock [10]

In output of ps -e I've see this process: 160 root [ESP_SPI_WORK_QU]

full ps -e output

I found line of code with same name of task: https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_ng/host/main.c#L813

Where I may wrong?

I have moved on, the device is detected, but another error occurs:

I've capture data exchange between Host-side and ESP32: DSLogic-la-230108-221959.dsl.zip

May view in DSView util

There is a first data since insmod esp32_spi.ko resetpin=128 command

Some text errors from Host side

@mantriyogesh Hello, could you help me please?

Apologies for the delay, will check it today and let you know..

Can you please:

Let us know if any changes you have done in the Linux side code?
Try commenting adjust_spi_clock() so as SPI freq will not change: https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_ng/host/spi/esp_spi.c#L216
Check if works if the SPI mode is changed to something other than 2 https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_ng/host/spi/esp_spi.c#L467

Logic analyzer log: DSLogic-la-230114-130408.dsl.zip

Thank you for investigating at your side & the analyser dump.

Observations

The MISO is working fine (This conforms that SPI Lines are behaving as they should). But The MOSI doesn't send anything.
Handshake was toggled but next transaction was never scheduled. Suspecting if Interrupt was raised / correctly handled for Handshake pin (also verify Data ready pin interrupt additionally)

Git Commit

Release you have used is ESP-Hosted-NG release 1.0.2 The Source code compatible for Linux side kernel building is at Source code (zip) I hope you are using same to build the code at Linux.

GPIOs

Next thing to confirm is GPIOs. Below steps will help verify if the GPIOs are working or not:

Three GPIOs needed -

Handshake pin: Please add a KERN_ERR log in https://github.com/espressif/esp-hosted/blob/release/ng-v1.0.2/esp_hosted_ng/host/spi/esp_spi.c#L76-L83
Data Ready from ESP to Host: Similarly, please add a KER_ERR log in https://github.com/espressif/esp-hosted/blob/29208b6c156be06dfd90dadc6dd43acd4d98d748/esp_hosted_ng/host/spi/esp_spi.c#L67-L74
ESP Reset pin: This pin will make sure ESP is reset on every fresh insert of kernel module esp32_spi.ko

Intention is to trigger next spi_sync_transfer() at https://github.com/espressif/esp-hosted/blob/29208b6c156be06dfd90dadc6dd43acd4d98d748/esp_hosted_ng/host/spi/esp_spi.c#L439 using spi_work

Reset PIN work normally, blue LED on ESP Dev Board disable after module insertion.

Also i found a bug. If I call rmmod, kernel crashed:

Okay. So interrupts are coming. But something is strange. Despite of the interrupts sometimes I do not see that the transactions are not happening. MOSI line doesn't behave as it should.

Are you using jumper wires? If yes, how long are they? If nothing works, We will go into debug mode, where I will have to provide binary with log and patch to use at Linux kernel module, to understand till what point the things are moving.

The capture looks not consistent with the general expectations. The Data ready is not high after ESP reset -> ESP is the one to do first transaction. so DR pin should be high at the first place. otherwise first transaction would not take place.

First thing is MISO on ESP reset (ESP needs to send data and will set DR high. On host's first transaction, MISO will be the receiver. Then further with next message exchanges, MOSI would have some data to send.

Without any transaction DR is going down?

Can you please verify if DataReady, Handshake and reset pin GPIOs are not used by other peripherals or alternatively change them to ones not in use? Wires for SPI should be < 10 cm, possibly 5-6cm or less.

Originally I used jump wires, but then reduce wire size. Now ESP32 and Host Dev Board are connected to the breadboard. SPI wires pins reduced maximally (1-2cm). But Handshake and Data Ready pins use jump wires (approx 15cm).

I can take a picture, if need, but everything is very confusing there, because of the connected logic analyzer.

Also worth cross checking if wire connections are not touching each other (in case manually cut and joined by hand) & connections are as per

For SPI you can have comfortable wire size like 5-6 cm. it is better if e have all wires at (almost) same length.. As I said, You can try these things first. Don't worry, we will get thing working. But might need debugging, which generally takes some time. worth to cross check the GPIOs not being used by any other peripheral, Connections exactly as per the documentation.

As you are anyway using ESP32, Just for trial, can you use NG release 1.0.1? For that, please use the source code from Source (zip).

Note: NG release 1.0.2 is not backward compatible. Use firmware binaries and 'Source Code(zip)' exactly from same release.

On Release 1.0.2

I reduce wires, see picture:

All the same, from launch to launch, the interface either appears or does not appear. Once I even managed to scan the network and get two access points on the output of the iw (although in fact there are many more).

The next step is to upload version 1.0.1 to the ESP32 and build the kernel module version 1.0.1?

1.0.1 to 1.0.2 there is design change. Just to understand from the issue perspective, if older release works for you or not.

There is one more possibility of using FG if in case cfg80211 is not must for you. NG is comparatively newer than FG. The FG solution has been present since very long and you should get it up easily. The hardware setup should be same. In case of FG you also can get access to the ESP source code.

For FG, if want to build and flash, can use master at both ESP & host. alternativly you can also use release binary and sourced code from release 0.0.5.

Have you tried any of these two?

But do I understand correctly that in the FG version I can't use wpa_supplicant and/or iw? Also, I could not raise the interface, is this also done differently in this version?

# ip link set ethsta0 up
ip: SIOCSIFFLAGS: Cannot assign requested address
# ip link set ethap0 up

That is correct. The FG is oriented to more of API based approach. It is not connected with wpa_supplicant or iw. It is solution where your user space application can create and maintain the wifi connection just by simple function calls. In contrast to wpa_supplicant, we have open sourced custom control path.

We created demo app which should be usable directly. In that you can use python based or c based applicantion, whichever is more suitable for your end application.

For the documentation, please follow https://github.com/espressif/esp-hosted/tree/master/esp_hosted_fg.

This is simple to use python app demo : https://github.com/espressif/esp-hosted/blob/master/esp_hosted_fg/docs/common/python_demo.md#demo-app-in-python. Check the gif or image in this page..

In this case, the FG version does not suit me. Can we return to fixing the problem with the NG version?

Positive about it. Is it possible to quickly try NG 1.0.1 ?

That is something with would let us know to focus if new code is to be suspected or not. Just repeating myself, please use source code from release 1.0.1 page for host side kernel buildingwhen you use 1.0.1 ESP firmware..

I've try it -> https://github.com/espressif/esp-hosted/issues/191#issuecomment-1384900360 Not working too:)

Okay. We will enter debug mode!

I will try to add logs and give you firmware and patch at Linux side. By the way, I observe that you use small and big wires combination. Is it possible to make them all same size by the time I get you above.

At the moment, all the wires involved in the operation of the driver are approximately the same length (see photo above). In the same photo above, there are 2 long wires - these are ground and power - should they be shortened too?

As you have FG setup already in place, can you just cross check the communication is working or not? This will rule out any issues with wires/communication as such. You just need to load the module, check first event (which you have got all working) and followed by Python based simple CLI command

I am giving you the debug binaries based on NG today.

Can I use the C sample program for FG? The target device is very compact characteristics, there is no python.

yes. that should be fine. any single command request say sudo ./test.out get_sta_mac_addr.

sudo ./test.out will list you all possible commands in C demo application.

2023.01.18_NG_gh191_debug_log.tgz Flash these binaries and apply the debug patch on host. Please refer readme.txt in tarball for detail.

Please note:

This is debug binary (with lot logs), not fit for production.
Bluetooth is disabled just for lowering the message exchange.

Have you received the commands in ESP side? ESP log please?

I suspect this more of timing issue. Can you reduce the freq to 1 MHz in https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_fg/host/linux/host_driver/esp32/spi/esp_spi.c#L33

and #define SPI_CLK_MHZ 10 in block to 1 https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_fg/esp/esp_driver/network_adapter/main/spi_slave_api.c#L47-L67

Let's first verify if this is timing issue. then we will get slowly with higher freq

Is I need to recompile esp-side code?

2023.01.18_NG_gh191_debug_log.tgz Flash these binaries and apply the debug patch on host. Please refer readme.txt in tarball for detail.

Please note:

This is debug binary (with lot logs), not fit for production.

Bluetooth is disabled just for lowering the message exchange.

I've try make host-side code with patch, but I have some errors

ERROR: "host_sleep" [/home/alexey/esp-hosted/esp_hosted_ng/host/spi.ko] undefined!
ERROR: "esp_deinit_interface_layer" [/home/alexey/esp-hosted/esp_hosted_ng/host/spi.ko] undefined!

ERROR: "esp_init_interface_layer" [/home/alexey/esp-hosted/esp_hosted_ng/host/spi.ko] undefined!

What is the git commit at host? Kernel version?

I applied the same patch on expected git commit again and captured the log for commands and output.

I suspect this more of timing issue. Can you reduce the freq to 1 MHz in https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_fg/host/linux/host_driver/esp32/spi/esp_spi.c#L33

and #define SPI_CLK_MHZ 10 in block to 1 https://github.com/espressif/esp-hosted/blob/fe0b10584417629908cee8141699c2f35ea05a25/esp_hosted_fg/esp/esp_driver/network_adapter/main/spi_slave_api.c#L47-L67

Let's first verify if this is timing issue. then we will get slowly with higher freq

Is I need to recompile esp-side code?

Yes. It s fairly easy. You need to setup ESP-IDF and build using it. Document tells how to do it. In case you need the binary images, let me know, I can prepare and send them to you. But testing FG must work, at least sample command. If you face issues there, you would face exact same issues in NG as well.

We suggest to change rpi_init.sh as per your Linux system (Very minimal changes like populating CROSS_COMPILE etc variables should be required). Anyway, instead of using MODULE_NAME=spi, try with target=spi
