3.3. Decision Firmware Data Max Retry Information

The only user accessible field from the decision firmware data structure is the max_retry value, stored as an 8-bit value at address 0x10018C in flash. The value in flash is actually max_retry - 1. That is, a value of zero means each image is tried just once.

Both U-Boot and LibRSU enable the max_retry option to be queried. For examples on querying the max_retry option for both U-Boot and Linux, refer to the Remote System Update Example section. The max_retry option must first be queried in U-Boot for the value to be available in Linux.
