Hi folks,
# U-Boot 2019.04 Configuration
I just updated to the latest version via git.
My previous version was the recent 2019.04-rc4.
Now in this latest version I think a bug shows up:
Inside Linux on the device, suddenly the following command no longer works:
# fdisk -l /dev/mmcblk0
fdisk: cannot open /dev/mmcblk0: Input/output error
# ls -l /dev/mmcblk0
brw-rw---- 1 root disk 179, 0 Jan 1 1970 /dev/mmcblk0
The device is present, but fdisk cannot read the partitions,
although u-boot has successfully used the boot partition
of this SD card to boot Linux.
IMHO a funny situation, isn't it? :-)
This always had worked for me, up until now.
Is this more a linux issue or a u-boot issue?
Let me know if you need specific data.
Thx

Sorry, seems to be a false alert.
After rebuilding u-boot it works fine again.
