I left some print statements in there mostly to illustrate the issue. Do you want those removed? Are there any plans to add logging crates? I briefly looked into creating some tests. Are there any existing test |
The current implementation uses the last 32 bytes of the bootloader file. When Secure Boot V2 is enabled, the bootloader is padded. The new implementation walks through the segments to find the end and adds the 16-byte aligned 1-byte checksum to update the SHA256 instead of incorrectly updating the padding. Closes esp-rs#715
