7.3.5.1. Corrupted Decision Firmware
This example uses U-Boot commands to demonstrate detecting that a decision firmware copy is corrupted, and recovering it by running a decision firmware update image.
Note: The commands listed in this example assume the initial flash image (JIC) was written to flash, with no other changes.
- Power cycle the board, boot to U-Boot prompt.
- Display the RSU status:
SOCFPGA # rsu status_log Current Image : 0x01000000 Last Fail Image : 0x00000000 State : 0x00000000 Version : 0x00000202 Error location : 0x00000000 Error details : 0x00000000 Retry counter : 0x00000000
The top four bits of the state field are 0x0 which means the currently used decision firmware index is zero. There are no errors.
- Display the decision firmware status:
SOCFPGA # rsu display_dcmf_status DCMF0: OK DCMF1: OK DCMF2: OK DCMF3: OK
The command compares the currently used decision firmware copy 0 with the other copies, and displays that all decision firmware copies are fine.
- Corrupt decision firmware copies 0 and 2:
SOCFPGA # sf probe SF: Detected mt25qu02g with page size 256 Bytes, erase size 4 KiB, total 256 MiB SOCFPGA # sf erase 0 0x1000 SF: 4096 bytes @ 0x0 Erased: OK SOCFPGA # sf erase 0x100000 0x1000 SF: 4096 bytes @ 0x100000 Erased: OK
- Power cycle the board, boot to U-Boot prompt, display the RSU status and decision firmware status:
SOCFPGA # rsu status_log Current Image : 0x01000000 Last Fail Image : 0x00000000 State : 0x00000000 Version : 0x10000202 Error location : 0x00000000 Error details : 0x00000000 Retry counter : 0x00000000 SOCFPGA # rsu display_dcmf_status DCMF0: Corrupted DCMF1: OK DCMF2: Corrupted DCMF3: OK
The currently used copy of the decision firmware is 1, as indicated by top four bits of the version field. The decision firmware copies 0 and 2 are detected as corrupted.
- Erase an unused slot, add the decision firmware update image to the slot, verify it was written fine, and confirm it is now the highest priority slot:
SOCFPGA # rsu slot_erase 2 Slot 2 erased. SOCFPGA # fatload mmc 0:1 ${loadaddr} decision_firmware_update.rpd 151552 bytes read in 9 ms (16.1 MiB/s) SOCFPGA # rsu slot_program_factory_update_buf 2 ${loadaddr} ${filesize} Slot 2 was programmed with buffer=0x0000000002000000 size=151552. SOCFPGA # rsu slot_verify_buf 2 ${loadaddr} ${filesize} Slot 2 was verified with buffer=0x0000000002000000 size=151552. SOCFPGA # rsu slot_get_info 2 NAME: P3 OFFSET: 0x0000000003000000 SIZE: 0x01000000 PRIORITY: 1
- Pass control to the devision firmware update image:
SOCFPGA # rsu slot_load 2
- The decision firmware update image writes new decision firmware copies and new decision firmware data to flash, remove itself from CPB, then pass control to the highest priority image.
- Stop at U-Boot prompt and confirm the decision firmware copies are all good, the decision firmware update image was removed from CPB, and the highest priority image is running:
SOCFPGA # rsu status_log Current Image : 0x01000000 Last Fail Image : 0x00000000 State : 0x00000000 Version : 0x00000202 Error location : 0x00000000 Error details : 0x00000000 Retry counter : 0x00000000 SOCFPGA # rsu display_dcmf_status DCMF0: OK DCMF1: OK DCMF2: OK DCMF3: OK SOCFPGA # rsu slot_get_info 2 NAME: P3 OFFSET: 0x0000000003000000 SIZE: 0x01000000 PRIORITY: [disabled]
