| 3 | # Script to burn entire 32MB of BMC SPI Flash |
| 4 | # |
| 5 | # Usage: |
| 6 | # a) Local: /run/initramfs/update_all <bmc-image-file> |
| 7 | # b) Remote: sshpass -p "<root-password>" ssh root@<ip> '/run/initramfs/update_all <bmc-image-file>' |
| 8 | # |
| 9 | # Assumptions: |
| 10 | # <bmc-image-file> is a 32MB file representing all partitions in BMC SPI Flash |
| 11 | # <bmc-image-file> exists on local filesystem |
| 12 | # /dev/mtd0 represents entire BMC SPI Flash device |
| 13 | # /dev/mtd5 is a JFFS2 filesystem (rwfs) partition |
| 14 | # /bsp/reset/bmc_upgrade is symlink pointing to proper sticky bit in CPLD |
| 15 | # |
