We are trying to integrate raspberry pi running linux (4.9.22-v7+) to murata 1CK (bcm4339) through SDIO.
1) bcm 4339 got enumerated successfully (SDIO-mmc)
2) brcmfmac driver gets loaded.
3) driver identifies binary files and nvram loads it to bcm4339
4) after which brcmfmac failed with the following error
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0xx 50
Attached entire dmesg logs. (Had to remove and reinsert brcmfmac with elevated debug level so some debug information is available)
Tried binary and nvram files from Quick Start with iMX6 Ultralite EVK and Mass Market Modules,
with which people had success with brcmfmac and bcm4339.
Any support is much appreciated,
