Hi
Have skoda 5Q0035819B unit, made by Preh. Update firmware from 0363 to 0367
After writing emmc with patched files with sd cardreader unit stuck in bootloop with next error:
xpt_configure: No sdmmc interfaces found
Unable to access "/dev/hd0" (2)
mount: Can't mount / (type qnx6)
mount: Possible reason: Invalid argument
mount: Can't mount /tsd/etc/swap_keys (type qnx6)
mount: Possible reason: Invalid argument
mount: Can't mount /tsd/var (type qnx6)
mount: Possible reason: Invalid argument
J5e.QNX.init.ready
on: No such file or directory (/tsd/bin/system/startup)
and 00018000 emmc error
Bacup restore didn't help
Emergency starts, but fail recovery from SD
Watch whats happen in DAT lines by oscilloscope - DAT0-DAT7 always high (+3.3)
On clk-cmd lines some data goes.
P.S. Help with values of two resistors on CLK/CMD lines (in red circle)
upd: problem solved, replace resistiors and unit back to work
