BIN file validation for OTA

[davdav]

Hi all,

I would like to do an OTA in this way:

-I download a BIN file from a server from my factory APP
-I store the BIN file in an SD card
-I read the file and validate the BIN file
-If the validation is OK, I read the file and write the ota partition APP

This seems feasible. What I would like to check is if the BIN file has not been corrupted during reception.
Is there a CRC (or other validation method) inside the BIN file generated by the compiler?

Thanks

I'm looking for the same functionally, did you find a solution?

Hi,
I solved using MD5 and calling my APP file as "myapp_<MD5string>.bin" where <MD5string> is a 32characters string composed of the MD5 hash.
