Please bump brcm/bcm4330-sdio.bin firmware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

As a week-end project I got the BCM4330 chip to work with the mainline Linux kernel on the MIPS CI20 board. One of the problems I was facing was the firmware crashing, resulting in timeout errors in the brcmfmac driver.

It turns out the bcm4330-sdio.bin firmware that's currently in linux-firmware is not the latest one. Running "strings" on the blob points out to a version 5.90.125.104 dated 2011-10-25. The firmware that originally came on the CI20 is version 5.90.195.26 dated 2012-05-09, and the version found in Android [1] is 5.90.195.114 dated 2013-01-23. Only the last two will work on the CI20 board.

My question then, could we bump the firmware available in linux-firmware to the latest version? Or is there a valid reason why an older firmware is kept in the tree?

Best regards,
-Paul Cercueil
