Hi, ajudge:
Now when we use RK3568 paired with FGH00MABMD for debugging, an error occurred as shown in the attached image after loading the driver. How can we resolve this issue?
These errors occur intermittently, sometimes appearing and sometimes not.
Hi @panhaojie,
-110 looks to be ETIMEDOUT on this system, which usually points to an issue with the hardware. The intermittent behaviour is concerning.
Can you capture a logic analyzer trace at a high sample rate (~250MHz)? Please capture all the SDIO lines, as well as the RESET line.
