esp-hosted not working with RPi3B+ & ESP-WROOVER-KIT

[multigiorgiplex]

Hi all,

I'm having issues running the esp-hosted firmware via SDIO. The syntomphs are a bunch of SDIO initialization errors on the host with a lack of debug output on the esp. In this archive there are logs of the both sides.

I suppose that the issue resides on the ESP firmware, because the SDIO errors that the kernel spits out are triggered when I enable the ESP board, which is being keeped idle until that moment via pulling the EN pin to GND.
Nothing seems to change when I run the rpi_init.sh script on the host.

Yes I double-checked the connections.
I also tried to use the HCI via UART connections, and the result is similar, no output from the ESP monitor and timeout on the host side.

Hi,
Thanks for the feedback. This looks like a setup problem. Please share your setup image with us. We will take a close look at it.
Meanwhile, please try following and let us know if that helps you.

• As per our experience, most of the time such issues are caused due to jumper wires. Please make sure to use smaller (in length) and good quality jumper wires.

• Please make sure to power ESP32 and Raspberry Pi separately with a power supply that provide sufficient power. ESP32 can be powered through PC using micro-USB cable. In case if you are using USB hub to power up, ESP32 and/or RPi, make sure that hub is externally powered.

Thanks

Thanks for the reply,

it was a setup problem, I removed the unreliable jumper cables by soldering wire traces on a perfboard.

Now the system works as expected.

Thanks for your time.
