Subject: [BISECTED] [BUG]: MMC initialization hang at Zynq Z-turn board
Hello,
I am running Zynq Z-turn board and I face the following issue with MMC initialization in SPL. With u-boot master, I see the message similar to the following:
U-Boot SPL 2019.07-00352-gb5f3eb3393 (Jul 31 2019 - 20:03:42 +0300) mmc boot Trying to boot from MMC1
Then, the u-boot waits forever. I've tried to add debug prints and found that execution is stalled somewhere inside mmc_init(). Using bisect I've found that the following broken commit is the following:
https://gitlab.denx.de/u-boot/custodians/u-boot-mmc/commit/41a9fab8dac841afb...
Would this patch help?
Yeah, this mostly looks like a NULL pointer access issue.
Unfortunately, 41a9fab8 doesn't help me.... :-( Behavior remains the same.
You need to implement the same thing with your driver (I assume you are using zynq_sdhci.c?). sdhci_setup_cfg() requires a valid host->mmc->dev. Move that assignment to above the sdhci_set_cfg() call in your driver.
Now it works. Thank you a lot! I'll prepare fixing patch for zynq_sdhci.c shortly.
Thanks, Faiz
