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.
Works when the device is running either osimage or bootloader.
- New memory reading command in osimage and bootloader.
- Extended 'hw readmem' command with length parameter, file writing and hex viewer.
- Introduced '--dumpmem' option to proxmark3 executable to support dumping from bootloader.
Simple interactive examples:
hw readmem -f flashdump
hw readmem -l 1024
CLI example:
./pm3 --dumpmem flashdump.bin
Reading from arbitrary memory ranges can be unlocked using the 'raw' option.
* Add `.ramfunc` section to bootrom loader script
* exclude spiffs functionality from flashmem.h/flashmem.c
(allows bootrom to use flashmem)
* hide unused tick.h / flashmem.h functions from bootrom
(not technically necessary; see comments)
* bootrom: add source files, include path, and defines when
`PLATFORM_DEFS` defines `WITH_FLASH`
* Define `AS_BOOTROM` to indicate code is building for bootrom
* .h include only the strict minimum for their own parsing
* this forces all files to include explicitment their needs and not count on far streched dependencies
* this helps Makefile to rebuild only the minimum
* according to this rule, most standalone .h are now gone
* big app.h is gone
* remove seldom __cplusplus, if c++ happens, everything will have to be done properly anyway
* all unrequired include were removed
* split common/ into common/ (client+arm) and common_arm/ (os+bootloader)
* bring zlib to common/
* bring stuff not really/not yet used in common back to armsrc/ or client/
* bring liblua into client/
* bring uart into client/
* move some portions of code around (dbprint, protocols,...)
* rename unused files into *_disabled.[ch] to make it explicit
* rename soft Uarts between 14a, 14b and iclass, so a standalone could use several without clash
* remove PrintAndLogDevice
* move deprecated-hid-flasher from client to tools
* Makefiles
* treat deps in armsrc/ as in client/
* client: stop on warning (-Werror), same as for armsrc/
Tested on:
* all standalone modes
* Linux
* use macros for versions
* activate UNDERSTANDS_VERSION in bootrom
* fix missing break; bug in bootrom
* force flash_load to reject images > 256k if bootloader not up to date
* move logic from flasher to flash
- Keep button pressed when powering to force entering bootloader
- Once in bootloader more, you can release the button
- When in bootloader mode (no matter how you entered that mode)
- One button press to quit bootloader mode and boot main image
