Add agent CLI commands and chunked write support#12
Merged
Conversation
CLI: `defib agent upload/info/read/write` commands with human+json output. - upload: boot protocol upload with SPL from OpenIPC U-Boot - info: query running agent - read: dump memory to file with CRC32 verification - write: write file to memory with CRC32 verification Client: rewrite FlashAgentClient with chunked write_memory (16KB blocks of 512B packets) to work within PL011 FIFO limits. Added read_memory, dump_memory, selfupdate, verify methods. Uses recv_response to skip stale READY packets. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary
Wire the flash agent into the defib CLI with
defib agentsubcommands.defib agent upload -c hi3516ev300 -p /dev/ttyUSB0— upload agent via boot protocoldefib agent info -p /dev/ttyUSB0— query running agentdefib agent read -a 0x41000000 -s 4KB -o dump.bin -p /dev/ttyUSB0— read memory with CRC32defib agent write -a 0x40200000 -i data.bin -p /dev/ttyUSB0— write memory with CRC32Client rewrite:
FlashAgentClient.write_memory()uses 16KB chunked transfers with 512B packets to work within PL011 FIFO limits on uncached DDR. Addedread_memory,dump_memory,selfupdate,verifymethods.Covers roadmap items 1 (WRITE chunking) and 2 (defib integration) from #11.
