dwmmc_rockchip fe320000.mmc: Unexpected CMD11 timeout
#1
Trying to install slackwareaarch64 on pinebook pro, following well documented video and web page, I have installed slackwareaarch64 on 3 rockpro64 successfully. This is one of the newer(?) PBP will itty bitty emmc switch.

Installed slackware u-boot, this boots but cannot find slackware installer on sd card in sd card slot.

dmesg shows

this is same output from dmesg booting manjaro and inserting same sd card in sd card slot

this is a new 
SanDisk Ultra 32GB UHS-I/Class 10 Micro SDHC Memory Card and I've tried 64GB also.

Using the same sd card with slackware installer in a usb sd card reader, the slackware installer will load the system.
