wlan0 not brought up when running "bash rpi_init.sh spi" #433

Open markmusil opened 1 month ago

markmusil commented 1 month ago

Hardware

Problem I followed the instructions on this page and made it to step 2.1 and to the subsection titled "Setting up the environment and getting started". At this point I have run bash rpi_init.sh spi on my raspberry pi 4 which is wired up to the esp32-c6 (see attached photo). I am told that wlan0 will be brought up. This does not happen. There is, of course, the regular wifi radio station wlan0 that the raspberry pi provides. I figured this might cause a conflict (2 wlan0) so I ran sudo ifconfig wlan0 down before running bash rpi_init.sh spi but still no new wlan0 shows up.

Any ideas of where I could be going wrong? As you can see from the photo there is a 10k pull up resistor between SPI CE0 and 3.3V. Could this be my problem? thumbnail_IMG20240718130801

Have tested on latest master?

markmusil commented 1 month ago

Yes, I pulled today. I am at commit number da21e36

Which version of raspberry pi OS should I be using? Do you have a version number?

Can you please attach full textual logs of:

Just use master at both ESP and host side .

Need to get RPI log from start of the boot.

Can you try FG master ESP and FG master kernel driver first?

mantriyogesh commented 1 month ago

I am not sure, but something is really wrong even before using esp32 kernel module. Can you please attach :

Also, is this Raspberry Pi fresh installed? or any changes in kernel done? Is this Rpi flashed using default image or something else, for example?

I will work on this.

Can you please attach /boot/config.txt

See attached

config.txt

is this Raspberry Pi fresh installed?

Yes I am using the latest raspberry pi 64 bit OS for Raspberry pi 4B with nothing else installed on the raspberry pi.

or any changes in kernel done?

No. I made sure to do what is shown on the guide here which is to say that I installed the raspberrypi-kernel-headers.

Is this Rpi flashed using default image or something else, for example?

Default Raspberry pi 4 OS

When I try to run bash rpi_init.sh wifi=spi bt=spi from esp-hosted/esp-hosted-fg/linux/host_control/ I get the following error:

fatal error: protobuf-c/protobuf-c.h no such file or directory

I am going to build protobuf myself from scratch but I don't think this is what is supposed to happen.

mantriyogesh commented 1 month ago

No no, you should not build it from scratch.

Just update the submodules recursively

What do you mean by

"Can you try FG master ESP and FG master kernel driver first?"

Are you suggesting that I switch to using FG? I want to use NG so that I can directly control the wifi interface using WPA_supplicant.

markmusil commented 1 month ago

So, even esp-hosted-fg isn't working. I ran the following command

_./rpiinit.sh wifi=spi bt=spi

And got an error in line 165 of rpi_init.sh "5090 segmentation fault sudo rmod esp32_spi &> /dev/null"

Is there a possibility of doing a video call to address this directly? Or would you prefer to just continue with this ticket?

Hello @markmusil ,

I regret the problem you faced.

Can you please send the full textual logs when you face this issue?

Aug9_dmesg_raspi.txt

mantriyogesh commented 3 weeks ago
  1. Logs related The Aug9_dmesg_raspi.txt log is not from start of the loading of Linux, so it is hard to understand where the issue started.

The log starts at [562.370665] time, I think your log is getting huge (due to crashes) and resulting in losing the log. Easy way, create a new terminal, and run on system bootup:

$ sudo dmesg -c
$ sudo dmesg -w # tail and follow the dmesg

before loading the esp32 kernel module

  1. Wrong firmware? Screenshot 2024-08-12 at 10 23 05 AM the firmware flashed seems to be SDIO, but you intend to use SPI. You can refer documentation to flash spi firmware.

  2. spidev was not removed: From your log, I see module linked in doesn't have esp32_spi. Also, there is entry of spidev Screenshot 2024-08-12 at 10 20 02 AM

The spidev was expected to be unloaded/removed for your /dev/spidev._._ in the setup step at : https://github.com/espressif/esp-hosted/blob/6ddb670edcf15108be92d7e8e4fc6f32542ef5e4/esp_hosted_ng/host/rpi_init.sh#L168-L173

Can you please check why spidev was not removed?

markmusil commented 3 weeks ago

Would you recommend using a different raspberry pi?

Firmware here, I meant ESP chipset firmware you had used to flash in step (2).

Correct use of documentation would avoid any such issues.
