Hello @shihui2014 ,

Thank you for using ESP-HOSTED.

As I see you are using 0.3, I recommend using latest release, 0.0.5.

Can you please confirm the source code git commit you are using for 0.3, at ESP side and Host side? Host and ESP side code is expected to be on same commit. If in case you are using released ESP binaries, 'source code.zip' from assets on same page is expected to be used for host side kernel module building.

[shihui2014]

i have use same verion, esp_hosted_firmware_esp32_sdio_uart_v0.3 and esp-hosted-release-v0.3, the pin cmd and all the data(dat0-dat3) mast 10K pullups?

[shihui2014]

Can you tell me kernel ,esp32 sdio work time sequence?

[mantriyogesh]

Okay. In your case, pull ups are required (mandatory) for sdio. See the [details)[https://docs.espressif.com/projects/esp-idf/en/v4.1/api-reference/peripherals/sd_pullup_requirements.html).

Can you help to provide logs at host (/var/log/kern.log or dmesg or /var/log/messages) and commands run at host and their output.

Kernel 5.4.3 should be okay. Can you please elaborate 'sdio work time sequence'?

Some milestones:

1. Most imp: porting guide. please check both, https://github.com/espressif/esp-hosted/blob/master/esp_hosted_fg/docs/Linux_based_host/porting_guide.md And https://github.com/espressif/esp-hosted/blob/master/esp_hosted_ng/docs/porting_guide.md
2. Getting sdio configured on your platform using say device tree
3. Add external pull ups
4. Connect esp to host using sdio lines
5. Burn esp with sdio binaries
6. While bootup of host, you should get CIS info printed (esp identified as sdio) with matching sdio instance as configured (in device tree)
7. Resetpin should be verified working
8. Load the kernel driver
9. Get the bootup / init event from ESP

CIS and bootup logs can be referred from https://github.com/espressif/esp-hosted/blob/master/esp_hosted_fg/docs/Linux_based_host/SDIO_setup.md#3-checking-the-setup-for-sdio

Getting platform configured is prerequisite for esp hosted kernel driver to work. we can help you in the process, but it largely remains outsides the scope of esp_hosted.

If you are no position to add pull ups, you can use alternative transport, spi, where pull ups are not required.

So from your log, I still suspect if the SDIO is detected or not. I would suggest to verify your device tree.

If the connections are correct and ESP is flashed with SDIO firmware, Host should detect the ESP SDIO first.

I am attaching working reference NXP imx 8mm (imx8mm-lpddr4-evk) dts for your reference. We are not expert of device tree, but we believe below files may point you in better direction.

To add further, After doing:

1. ESP <== SDIO ==> Host connections made
2. Device tree mmc instance enabled (with correct/default pinctrl)
3. ESP flashed with SDIO binary

Your expected host side log (without even loading ESP32 host kernel module):

/var/log/kern.log or /var/log/messages or dmesg would contain:

[   77.649578] mmc1: queuing unknown CIS tuple 0x01 (3 bytes)
[   77.657019] mmc1: queuing unknown CIS tuple 0x1a (5 bytes)
[   77.660243] mmc1: queuing unknown CIS tuple 0x1b (8 bytes)
[   77.662448] mmc1: queuing unknown CIS tuple 0x80 (1 bytes)
[   77.662545] mmc1: queuing unknown CIS tuple 0x81 (1 bytes)
[   77.662643] mmc1: queuing unknown CIS tuple 0x82 (1 bytes)
[   77.664445] mmc1: queuing unknown CIS tuple 0x80 (1 bytes)
[   77.664541] mmc1: queuing unknown CIS tuple 0x81 (1 bytes)
[   77.664637] mmc1: queuing unknown CIS tuple 0x82 (1 bytes)
[   77.664832] mmc1: new SDIO card at address 0001

Once you have detected the SDIO, then, you would want to port rpi_init.sh script as per your host (porting guide mentions this). This should be simple enough. then you can load the esp32_sdio.ko driver with 'resetpin' configured using ported rpi_init.sh.

Once the kernel module loaded, you can see ESP has reset (using resetpin). Host will show log similar to:

[   77.665287] esp_probe: ESP network device detected
[   77.877892] Features supported are:
[   77.877901]   * WLAN
[   77.877906]   * BT/BLE
[   77.877911]     - HCI over SDIO
[   77.877916]     - BT/BLE dual mode
[   78.096179] esp_sdio: probe of mmc1:0001:2 failed with error -22

mmc instance will vary.

Hello @shihui2014

Were you manage to get CIS & first event like above?

[shihui2014]

hello @mantriyogesh I haven't got this infomation。

[shihui2014]

hello @mantriyogesh I haven't got this infomation。

[mantriyogesh]

I think you can cross check your Linux SoC MMC config (Device Tree). We cannot assess your Device Tree to be correct or not (It varies from SoC to SoC)

If that is correct, ESP is connected correctly with expected pull-ups & ESP flashed with correct(matching) firmware, then you can expect the CIS prints.

You can also verify if (1) CIS is originated from ESP or not by shut the power to ESP -> No CIS for mmcX. (2) Power ESP -> CIS for mmcX printed in host log.

Make sure you reboot host to check CIS prints in both above tests (If device tree is not correctly configured/supported to poll the SD MMC hardware detection)

host log could be one from /var/log/messages or /var/log/kern/log or dmesg command.

[shihui2014]

okey， I'm going to use ESP-Hosted-FG-release 0.0.5，

[mantriyogesh]

Okay, that will be easy to integrate actually. You can embed your expected calls right from application.

But even in that case, the underlying sdio hardware still needs to be configured (https://github.com/espressif/esp-hosted/issues/212#issuecomment-1469472003 is still applicable)

[shihui2014]

hi,@mantriyogesh ,thank you for your support, When see this information,"esp_sdio: probe of mmc1:0001:2 failed with error -22 ", What should I do next?

[mantriyogesh]

esp_sdio: probe of mmc1:0001:2 failed with error -22 can be ignored. we don't use function 2 so returns.

What is concerning, process_rx_packet, Dropping unsupported serial frame

[mantriyogesh]

What is output of

$ git log --oneline | head -2 

at ESP (if building from source) and Host side? It should be https://github.com/espressif/esp-hosted/commit/d30942e7d863a78c1ea2d13c0f964529ff542fef

Can you use current master at both sides, ESP and host side? https://github.com/espressif/esp-hosted/blob/81778f63a9d84fa46f8a907078f9e2681b391bf5/esp_hosted_fg/esp/esp_driver/network_adapter/main/sdio_slave_api.c#L183-L202 You can tune timing there.

[mantriyogesh]

Are you able to check ahead if you are able connect to AP (using demo app)? Capture logs at both, ESP and Host.

• ESP
  • idf.py monitor OR minicom log
• Host:
  • dmesg OR /var/log/messages OR /var/log/kern.log
  • Commands run and their output

[shihui2014]

I visit the website" https://github.com/espressif/esp-hosted/releases " and download ESP-Hosted-FG-release_0.0.5.tgz ,esp-hosted-release-fg-v0.0.5.zip

[mantriyogesh]

yes perfect. Can you try this and get logs at both sides?

[shihui2014]

hi @mantriyogesh you say “connect to AP (using demo app)?” the demo app is？

[shihui2014]

connect to ap use by “esp-hosted-release-fg-v0.0.5\esp_hosted_fg\host\linux\host_control\ c_support ”？ may i use “c_support” only？Because my board has no python environment。

[mantriyogesh]

I don't see your ESP full log. Can you please help to get ESP log from flashing till end? I suspect you are still using old release.

[mantriyogesh]

Yes you can use C demo app from esp_hosted_fg\host\linux\host_control\c_support.

[mantriyogesh]

Log at host, Dropping unsupported serial frame can only comes at line 423:

https://github.com/espressif/esp-hosted/blob/81778f63a9d84fa46f8a907078f9e2681b391bf5/esp_hosted_fg/host/linux/host_driver/esp32/main.c#L409-L424

Have you checked the file mentioned in https://github.com/espressif/esp-hosted/issues/212#issuecomment-1471255862

You might want to re-run rpi_init.sh (unload and cleanup the kernel driver and rebuild and load it back after above changes) Revert any timing related changes if you have done at ESP side.

[shihui2014]

i have define CONFIG_SUPPORT_ESP_SERIAL =1 in esp.h so line 423,will not appear, Now the question is [ 1104.401391] esp_sdio: probe of mmc1:0001:1 failed with error -16 [ 1104.407978] esp_sdio: probe of mmc1:0001:2 failed with error -16

[shihui2014]

my makefile is ， obj-$(CONFIG_WLAN_VENDOR_ESP32) += esp32_sdio.o esp32_sdio-objs:=esp_sdio.o esp_bt.o main.o esp_sdio_api.o esp_stats.o esp_serial.o esp_rb.o and i have define CONFIG_SUPPORT_ESP_SERIAL =1 in esp.h ，This works the same way as CONFIG_SUPPORT_ESP_SERIAL = y

[mantriyogesh]

Current code changes please? $ git status $ git diff

Both ESP and Host side?

Also are you getting first event at Host (host log) will tell. It will be important to understand if the esp_probe is being called or not and where it is failing. similar issue and some explanation with logs addition: https://github.com/espressif/esp-hosted/issues/198#issuecomment-1463210942

[shihui2014]

I have used the latest code for esp side ,but where can i download esp bins file for host side?

[mantriyogesh]

esp bins file for host side

0.0.5 work with latest current master 81778f6

But as you need might want to change the timing, You will need to flash from source. It is easy to flash using source (and much usable as well).

If you need binaries only, Let me know. I will get you FG 0.0.5 based binaries with timing adjusted (as above mentioned in https://github.com/espressif/esp-hosted/issues/212#issuecomment-1469789618)

[mantriyogesh]

Regarding https://github.com/espressif/esp-hosted/issues/212#issuecomment-1471382604, Can you please localise by adding prints in esp_sdio.c, which call fails? Is the esp_probe() even entered once after loading module?

shows your sdio is fine. It has received the init event as well.

Have you ported the rpi_init.sh to your platform as per stated in porting)guide?

[shihui2014]

esp_hosted_fg\host\linux\host_control\c_support
Makefile SRC += $(DIR_COMMON)/protobuf-c/protobuf-c/protobuf-c.c the file protobuf-c.c dos not exist,so i can't compile c_support

[mantriyogesh]

Have you checked this? https://user-images.githubusercontent.com/67477199/225508224-c7b22446-abde-4c9d-92aa-ce4968e9ac39.png

[shihui2014]

I don't understand what you mean? I'm not using Raspberry-PI, so I can't use./rpi_init.sh directly on my board I need to compile c_support first, then download it to the board and run c_support, protobuf-c.c was missing when I compiled c_support

[mantriyogesh]

I know that you are not using Raspberry Pi. But to build the code, you will still need full esp-hosted repo. That includes submodules.

Where you have ESP-Hosted cloned, please update submodules as shown command in picture. You should be able to find protobuf-c.c file after updating submodule.

rpi_init,sh is of course Raspberry Pi specific. But when you still need to port it as per your platform. Basically, remove the things that are raspberry Pi specific but keep generic linux. As I see you are interested in UART, still I suggest you to first get SDIO only working.

For UART, you may need to port rpi_init.sh to make you SoC UART GPIOs in correct alternate function. Please check https://github.com/espressif/esp-hosted/blob/master/esp_hosted_fg/docs/Linux_based_host/porting_guide.md#122-rpi_initsh

Great. You can now integrate the APIs into your application and control the ESP-Hosted right through your application.

Please do check ctrl_apis.md and serial_apis.md for all APIs from https://github.com/espressif/esp-hosted/tree/master/esp_hosted_fg/docs/common
