Dear Simon & Ulf,
In message CAPnjgZ2MH8W05zgHsHXN=ETkEi2hNNZkXk6KdRnet0RebGxXqw@mail.gmail.com you wrote:
- Is there a possibility to check the signature/CRC before copying the
image to ram with imxtract?
I'm not sure of the specifics here - sometimes the image must be decompressed, etc. so in principle this is tricky to implement (but not impossible). Another option might be to zero it afterwards if the check fails?
Maybe I misunderstand the question, but: in any case we have to read the image from a storage device into memory to be able to look at the data, which is obviously needed for computing a checksum or signature.
Best regards,
Wolfgang Denk
