I'm using the one from repository now, yes.
Using the firmware I had from before, the only difference I see is the
time of when
the IRQ handler is called, but that is probably just randomness, I guess?
I think both firmware is fine. I was referring to the
brcm/bcm4329-fullmac-4.txt It's a nvram file contains critical
information used by firmware. And it's hardware dependent. We have
submitted a patch to remove the one in Linux firmware repository to
avoid confusion as it's for a Broadcom internal development board. It
may not work with your set up. I think there should be a similar file
comes with the proprietary driver package if you are using a module
instead of a 4329 chip. Please use that one.
Attached is the log when modprobing with old firmware.
The issue you facing is more likely SDIO bus connection issue.
brcmf_sdioh_request_word: Failed to write word, Err: 0xffffffac
mmc1: Got data interrupt 0x00200000 even though no data operation was in
progress.
These may be both caused by data CRC error/time out.
I don't have Exynos 4210 spec. But I guess for a such new chip the SDIO
host should be able to run the bus at 50MHz. You could try to hack the
MMC/SDIO host driver and reduce the max frequency to 25MHz or even
further to 12MHz to see if any improvement.
