AWR1642: When is CRC in the binary file used?

Part Number: AWR1642
Other Parts Discussed in Thread: UNIFLASH

Hi,

There are CRC section in the binary file.
Does the bootloader or Uniflash read and check this CRC to load the binary?
For some reasons, if the binary file is modified and wrote into the flash, CRC may not match and what is happened?

Best Regards,

Hi,

I found that the following sentense in the image creator user guide:

This step ensures an integrity check while the image is being downloaded to the SFLASH assisted by the bootloader.

This means the CRC is used during downloading from SFLASH.

Best Regards,
