The OLD frame size was tied to the NG one, but the bootloader only speaks OLD - growing PM3_CMD_DATA_SIZE would silently change sizeof(PacketCommandOLD) and break flashing against every deployed bootrom in both directions. Pin the OLD structs to their own constant and use it on every OLD path: reply_old and the OLD receive branch on both sides, the bootrom, and the flasher's write_block/send_finish_write_cmd, which memcpy into a PacketCommandOLD using the NG size. No behaviour change - both constants are 512 and armsrc .text is byte-identical before and after.
