Question about md output

Dear all,

I need to access data values stored in flash for integrity checking.

Thus, I would like to parse the output of md (memory display) and store its output to enviromental varaibles.

For example, when invoking:

=> md 0x100000 1
00100000: 8083764e bd86200a 60a19054 2c12c402

I would like to store one ore more memory values in some env variables.

1) Is it feasible with the current uboot scripting features?

2) Would it be possible to modify the md command so that it also store its output to env variables?

3) Or, would it be possible to modify the md command so that its output is just a word value which can be used for uboot scripting capabilities? e.g.

=> md 0x100000 1 2
bd86200a

=> md 0x100000 1 4
2c12c402

Best Regards,

FF

Dear "ffileppo at libero.it",

This is something where teh test / itest commands come in handy.

This is probably the wrong approach to do what you have in mind.

No. But actually it is not needed either. Use itest instead.

It would be possible, but it makes little sense to me.

Ditto.

Have a look at itest; if you still make no progress then please describe what you actually want to do, so we can show you how to do it efficiently - without need to modify code.

Best regards,
