I accidentally set uname_r to something bad in /boot/uEnv.txt. It took me an 
hour to figure out what U-boot was doing and to painstakingly re-create that, 
fixing uname_r and then booting the system.

Is there an easy way to override uname_r in /boot/uEnv.txt on the eMMC (or dtb)?

Also, how do you set really long environment variable values via the serial 
console in U-boot?

Thanks,
