CAN bootloader AN2662
54/83 Doc ID 14156 Rev 1
Note: When writing to the RAM, care must be taken to avoid overlapping the first 4Kbytes
(0x1000) in RAM because they are used by the bootloader firmware.
Note: No error is returned when performing write operations on write protected sectors.
Write operations to FLASH/SRAM must be word aligned, if less data are written the
remaining bytes must be filled with 0xFF.
Figure 40. Write Memory command via CAN: Host side
Note: If the start address is invalid, the command is NACKed by the device.
