Issue or Suggestion Description

请问esp-hosted-ng支持的linux内核版本是？支持树莓派最新的系统吗？测试使用的是哪个版本的OS？

[mantriyogesh]

Yes, latest Raspberry Pi OS is supported with ESP-Hosted.
Let us know if you face any issues.

请问这样是装好了吗？但是找不到wlan0，还需要设置哪里？

[mantriyogesh]

Check the dmesg in the linux.

The sdio should be enabled as per documentation.

1. Ensure that the $${\color{orange}external\ pull-ups}$$ are added with $${\color{yellow}expected\ values}$$ and on $${\color{yellow}expected\ lines}$$
2. Do $${\color{orange}not\ use\ jumper\ wires}$$ to connect SDIO lines. Always design and use PCB for SDIO. SDIO becomes a lot noisy and hard when using jumper wires.
3. Troubleshoot guide for some common issues
4. $${\color{yellow}/boot/config.txt}$$ or $${\color{yellow}/boot/firmware/config.txt}$$ is correctly configured as per documentation
5. If you follow (1) & (2), send us camera photo showing the connections.
6. If you wish to use jumper cables, strictly use SPI only.

我用的是ESP-WROOM-32模块，执行sudo bash rpi_init.sh sdio后显示上图的错误

[VegardCheng]

还有这里应该没错吧

[mantriyogesh]

1. Send us the camera photo of connections
2. Try to erase the flash at ESP32. As you are using ESP32, please check the extra steps of $${\color{yellow}efuse\ burning}$$ in addition to the $${\color{yellow}external\ pull-up\ (>=10kOhms)}$$ on D0-D3, CMD lines. PCB only. $${\color{yellow}Strictly\ No\ jumper\ cables\ For\ SDIO}$$

To erase flash,

esptool.py --chip esp32 -p <esp chip usb serial port> erase_flash

eFuse burning and external pull-ups explained here

我做了这样一块底板连接树莓派CM4 IO
使用的是CM4（带EMMC，没有WIFI）

擦除重新烧录还是一样

[mantriyogesh]

PCB looks fine. https://pinout.xyz/pinout/sdio.

Although this is not the current issue, I see that the input power looks to be shared in between Raspberri Pi and ESP.
Please check the minimal power rating for your Raspberry Pi and ensure the input voltage and current ratings are supported by both adapter and the power cable used.

If you are mounting the esp dev kit, ensure as many grounds are short with raspberry pi ground. Can you power the esp individually?

If ESP can be disconnected from raspberry pi (take it out from pcb) and flash individually, still this error observed?

[VegardCheng]

单独上电显示的是这些信息

[mantriyogesh]

Please ensure you use $${\color{yellow}latest\ master}$$ at $${\color{orange}both}$$ esp and host both sides. $${\color{orange}Strictly\ exact\ same\ commit.}$$
If the esp is able to boot individually but not when connected, some issue in the connections might be there.

Check if raspberry pi pin 31 (reset/EN) pin is connected correctly and not floating.

I also note $${\color{red}Brownout\ detector\ was\ triggered}$$ in ESP log. This circuitry is not equipped with sufficient power.
Power ESP and Raspberry Pi individually.

$${\color{yellow}The\ input\ power\ rating}$$ for $${\color{yellow}both}$$ devices must be abided. Otherwise, you would crash or extremely low performance on the SDIO lines.

Also check $${\color{yellow}power\ available\ on\ SDIO}$$ lines after connection to raspberry pi. If it is less than 3v3, it would not work.

$${\color{yellow}eFuse}$$ burning might be required at ESP32. eFuse burning

我把上拉电阻换成51k后能跑到这，但是还是找不到wlan0

那几个上拉的引脚都能测到是3.3V，除了esp32的这个：

[VegardCheng]

windows有配置eFuse的软件吗？

[mantriyogesh]

You do not need extra software. ESP-IDF would be already available at your side. use espfuse.py from idf as mentionedin the document., https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/sd_pullup_requirements.html#conflicts-between-bootstrap-and-sdio-on-dat2

[VegardCheng]

这样是设置好了？
还是没有wlan0

[VegardCheng]

多了一句set up done，这是初始化好了？
