Peculiar problem executing boot.scr

Peculiar problem executing boot.scr

[Tasos Terzidis]

Hello,

I have a very peculiar problem.

I have a very simple boot.scr script so that u-boot can load it and run it.

My set up is a Raspberry 3 B (32 bit)

Sript is

Fatload mmc 0:1 ${kernel_addr_r} kernel7.img

Bootz ${kernel_addr_r} - ${fdt_addr}



When u-boot stops autocounting, finds the script loads it and the error
message is

-à    ‘ailed to find kernel7.img     ß--



Instead of F for word Failed, prints ‘ailed.



If I stop auto counting and enter the commands of script by hand it runs
and loads kernel as expected



As a matter of fact whatever command I add to the script gives an error

Example : if I add printenv the error is “can not find command”



I can not understand what the problem is.



Has anyone encountered such a problem ??



Thank you



Tasos

Can you post the whole console output so we can see version, etc.?

I cannot immediately even find that 'Failed to find %s' string in U-Boot.

This seems to be a mystery. Probably need to debug U-Boot and narrow
down what is happening. I assume that the board is reliable.
