u-boot flashing problem
#1
Hello,

I just flashed the eMMC with the u-boot.itb idbloader.img from Debian testing.

I might have mistaken to copy over the dd commands to flash the eMMC.

When I pressed the power-on button I get immediately on the serial port the u-boot output:

U-Boot TPL 2021.10+dfsg-1 (Oct 10 2021 - 04:20:52)
Channel 0: LPDDR4, 50MHz

Trying to boot from BOOTROM
Returning to boot ROM...

U-Boot SPL 2021.10+dfsg-1 (Oct 10 2021 - 04:20:52 +0000)
Trying to boot from SPI
Trying to boot from MMC2
Card did not respond to voltage select! : -110
spl: mmc init failed with error: -95
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###


Event when I plug-in the SD Card, the output is identical. Any idea how to solve this?

Disable/remove emmc,, since bootrom searches SPI, emmc, sd (in that order)
for idbloader and later rest of uboot package
There is no 'magic' keystoke to skip emmc
