A method of updating programmable device configuration code stored in
EEPROMs of a system is operable on complex systems having separate
management and system processors. The method includes executing a sequence
for updating programmable device configuration code on a management
processor of the system including erasing the EEPROMs, writing at least
one block of configuration code to the EEPROMs, and checking for errors
after writing. The errors checked for include failure of a FIFO to empty.
Upon detecting errors, the method includes automatically retrying writes.
Embodiments of the method are operable on systems having multiple serial
busses interconnecting EEPROMs to a common configuration logic, and on
systems having multiple management processors each capable of accessing
the common configuration logic.
