JLinkExe -device JADE_PHI_P47_01 -if JTAG -speed 1000 halt Verify the program counter has stopped. If not, recheck recovery mode entry. The P47 01 reserves the first 128KB for the factory bootloader (do not erase this). Everything after must be cleared.
jade-phi audit --export patches.json to document exactly what patches existed. This helps in legal or compliance scenarios. Q: Will removing all patches delete my application logic? A: Yes. Any user programs, ladder logic, or custom scripts stored in the user partition are considered patches if they differ from factory. Back them up separately beforehand. jade phi p47 01 removing all patched
setenv shadow_flash 0 saveenv For mission-critical environments where "removing all patched" must be absolute, consider these professional techniques: 7.1. Chip-off Reprogramming Physically desolder the SPI flash and EEPROM, read them externally, manually zero every non-boot sector, then resolder. This is the only 100% guaranteed method but requires rework skills. 7.2. Fuse Blowing for Permanence On P47 01 models with OTP (one-time programmable) fuses, you can blow the "patch enable" fuse after cleaning. This permanently disables the patch engine, ensuring no future patches can be applied or resurrected. 7.3. Forensic Patch Audit Before removal, run: JLinkExe -device JADE_PHI_P47_01 -if JTAG -speed 1000 halt
