Subject: [PATCH] brcmfmac: sdio: Increase the default timeouts a bit
|
|
|
|
On a Radxa Rock2 board with a Ampak AP6335 (Broadcom 4339 core) it seems
|
|
the card responds very quickly most of the time, unfortunately during
|
|
initialisation it sometimes seems to take just a bit over 2 seconds to
|
|
respond.
|
|
|
|
This results intialization failing with message like:
|
|
brcmf_c_preinit_dcmds: Retreiving cur_etheraddr failed, -52
|
|
brcmf_bus_start: failed: -52
|
|
brcmf_sdio_firmware_callback: dongle is not responding
|
|
|
|
Increasing the timeout to allow for a bit more headroom allows the
|
|
card to initialize reliably.
|
|
|
|
A quick search online after diagnosing/fixing this showed that Google
|
|
has a similar patch in their ChromeOS tree, so this doesn't seem
|
|
specific to the board I'm using.
