Hi, I'm working on a custom board with cyw4343 connected to osd3358-sm (TI am3358), when I load the brcmfmac driver I get 'HT Avail timeout' error. The same combination of driver+firmware works fine on Raspberry Pi Zero W. I've tried to gather as much information I can from both; the custom board and pi. This is available here: https://www.dropbox.com/s/vqejyrixbxx1z8d/logs.tar.gz?dl=0 I have a custom board with cyw4343 chip fitted and also flyleded Murata 1DX to the PocketBeagle, both give the same error code. My setup is as follows: osd335x-sm (TI am3348), cyw4343, 37.4 MHz xtal. Linux beaglebone 4.14.93-bone17.1 #1 PREEMPT Mon Feb 25 16:27:58 UTC 2019 armv7l GNU/Linux brcmfmac: cypress v4.14.52-backports brcm43430-sdio.bin: Version: 7.45.98.38 Is there something obvious which I'm doing wrong? Can you give me a hint on how to move with this further, please? Kind regards, Krzysztof
