How to print memory variable in U-boot?

i have the following lines in my U-boot environment:

ram_crc=10e00000
check_rd=if itest.l *$ram_crc == $crc_rd; then bootm $kernel; else run fail_h; fi

The comparison works. But how can i echo the contents of the memory address 10e00000?

I tried to print in the failure handler:

set fail_h echo $ram_crc

but when i print the environment i can see that it has replaced the variable with the memory address:

fail_h=echo 10e00000

How can i print the contents of the memory address?

Thanks!

Answer

For printing ‘contents of the memory address 10e00000‘ try:

 md 10e00000 1

or by using variable:

 md  ${ram_crc} 1

Where 1 is the wanted length of the dump.
