Dear Wolfgang,

thanks for your support.
Let me understand if I get this right.

for example, I have a block of 8 words, starting at 0x0:

00000000: a b c d
00000010: e f g h

where a is the crc32 computed on b,c,d,e,f,g,h

Within uboot, I would like to compute the crc32 of  b,c,d,e,f,g,h and compare 
it with a.

-- Compute CRC and store at address 20
crc 1 7 20
-- Compare CRCs
if itest *0 == *20; then echo CRC ok; else echo CRC bad; fi


Is that correct?

Thanks and best regards,

FF
