Hi all,
I am trying to get the Silex SC-SDCAC Wi-Fi SD card, which has a QCA9377-3, working on my system. This is on an i.MX 8ULP dev board, which exposes SDIO/MMC connections over an M.2 connector. Between the Wi-Fi module and the dev board is an M.2 to SDIO adaptor, which just passes through the SDIO CLK/CMD/DATA pins, GND, and VCC. My Linux kernel version is 5.15.53. I am using the ath10k driver as it should support driving the QCA9377 over SDIO. The linux development is being done with Yocto.
The MMC bus is able to detect the QCA9377 and the ath10k starts initializtion. However, there seems to be an issue with the firmware and/or board files. I am using linux-firmware 20220509 from https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git. Specifically, I am installing board.bin, board-2.bin, firmware-sdio-5.bin, and notice_ath10k_firmware-sdio-5.txt from ath10k/QCA9377/hw1.0 to /lib/firmware/ath10k/QCA9377/hw1.0/ on my target rootfs.
As seen at the bottom of this post, the MMC bus can find the SDIO card just fine. I verified that the firmware version is as expected, but then it fails to fetch the board data from board-2.bin. Is there a lack of this board in the upstream for this board file? There then seems to be a bunch of timeout/busy errors when attempting to drive the QCA9377. I think this could be a card firmware issue, but may not be.
Can anyone provide some assistance on what the issue may be?
Thanks,
Anthony

Hi Anthony,
This forum is only from QCA9377 SW support for the driver downloaded from qualcomm.com.
ath10k is an open source driver and recommend you to use ath10k forums to resolve your issues.
Thanks.
Hi Anthony,
try the [email protected] list or contact Kalle Valo [email protected], the maintainer ot the ath10k.
If you need some payed support I can recommend Fabio Estevam from DENX [email protected]. Please contact Wolfgang Denk [email protected] for a quotation.
Hi ddeepakk,
Sorry about that, I will reach out to the ath10k maintainers.
Hi wolfram.wadepohl,
Thanks for the resources! I appreciate it.
