Hi @evgyank2025
I did see those logs:
This line indicates that the host (RPi) is unable to put our chip into SPI mode. This typically indicates a hardware problem, and usually either an issues with the signal integrity of the SPI lines, or the reset line is not being controlled correctly.
Note that 20cm is actually quite long, especially when we’re dealing with fast rise times on data lines and the SDIO over SPI timing specifications (see Part 1 Physical Layer here. Are you able to reduce this to say, 6cm?
Using that image also won’t work with the WM1302 pinout, as the device tree handed to the kernel is for a Morse Micro hat used in our EKH01 kit - schematics here.
Given you have a debug board, I would recommend continuing trying with that board, and much shorter cables, using the image from Heltec and the pinout they describe.
If you want to use the WM1302 RPi hat, then you will need to modify the device tree overlay as described at the end of Build Thread: HaLow for Raspberry Pi OS
