PinePhone Beta Edition will not boot from MicroSD card

[skandigraun]

Same here. Got myself 2 SD card extenders, but after popping in one of them, my Pinephone stopped booting from sd card, referring to error -123.

Finally managed to get it back to business by compiling u-boot with the above mentioned CONFIG_MMC_BROKEN_CD option, and modifying the device tree for the kernel: removed cd-gpios, and added broken-cd to mmc0's node:

Code:

This way I can boot my own system from SD card again... thought would have been nicer if it doesn't break at all. Anyway, I'm off to give my extender a healthy dose of sandpaper.
