| Feature | Description | |---------|-------------| | | Host and target exchange X.509 certificates; each verifies the other's public key. | | Encrypted Transfer | AES‑256‑GCM protects payload confidentiality and integrity. | | Firmware Signing | Application images must be signed with the OEM’s private key; the bootloader validates the signature before commit. | | Anti‑Rollback | Version numbers are stored in a protected register; the bootloader rejects images with older version identifiers. | | Secure Erase | Optionally wipes unused flash pages to mitigate data‑leakage. | LINK-- Download Flash Loader 7.2.4 Sec 2.4 Lite And Slave
| Symptom | Likely Cause | Remedy | |---------|--------------|--------| | Handshake timeout | Wrong bitrate, missing driver, or target not powered | Verify physical connection, check driver status ( canconfig can0 up , ifconfig eth0 ), power‑cycle target. | | ERR_SEC_AUTHFAIL | Host certificate not recognized by target (expired, wrong CA) | Re‑import updated certificates from OEM; confirm date/time on both host and target. | | Flash aborted at 45 % | Insufficient flash space or write‑protect bits set | Use OEM’s memory map to select correct flash region, or disable write‑protect via configuration register. | | Verification failed | Corrupted image or signature mismatch | Regenerate the signed image; run openssl dgst -sha256 -verify <pubkey> -signature <sig> <file> to test locally. | | CLI returns “unknown option --auth” | Using an outdated version of Lite | Upgrade to the latest 7.2.4 release; older builds lack the --auth flag. | The tool is often divided into "Lite" and
