Unable to flash - bootrom issue

Hi,

I received a new PM3 recently and flashed the osimage up to r671. I now seem to be stuck with that version as I can no longer use the flasher.exe because the bootrom doesn't support the new flasher:

$ flasher COM10 /c/proxmark3/armsrc/obj/osimage.elf
Loading ELF file 'c:/proxmark3/armsrc/obj/osimage.elf'...
Loading usable ELF segments:
1: V 0x00110000 P 0x00110000 (0x00012656->0x00012656) [R X] @0xb8
2: V 0x00200000 P 0x00122658 (0x000029b8->0x000029b8) [RWX] @0x12710
Note: Extending previous segment from 0x12656 to 0x15010 bytes
Note: 0x2-byte hole created

Waiting for Proxmark to appear on USB... Found.
Entering bootloader...
(Press and release the button only to abort)
Waiting for Proxmark to reappear on USB................ Found.
Note: Your bootloader does not understand the new START_FLASH command
      It is recommended that you update your bootloader


Flashing...
Writing segments for file: c:/proxmark3/armsrc/obj/osimage.elf
 0x00110000..0x0012500f [0x15010 / 169 blocks]

And then nothing happens, it does not seem to be able to start the write process without the START_FLASH command.

The older flasher, this one from r486, does not seem to be able to find the device at all, probably because of the updated osimage.elf:

Loading ELF file '..\Firmware\bootrom.elf'...
Loading usable ELF segments:
0: V 0x00100000 P 0x00100000 (0x00000200->0x00000200) [R X] @0x94
1: V 0x00200000 P 0x00100200 (0x00001828->0x00001828) [R X] @0x294

Waiting for Proxmark to appear on USB...................................

and it never appears

Does anyone know of another way that I can update the bootrom? I did read an article about holding down the button during boot when using an old bootrom, but bot sure if this applies to the version that I have. It doesn't seem to work for me.

Here are my versions:

proxmark3> hw ver
#db# Prox/RFID mark3 RFID instrument
#db# bootrom: svn 486-unclean 2011-08-28 18:52:03
#db# os: svn 671 2013-03-09 15:43:42
#db# FPGA image built on 2009/12/ 8 at  8: 3:54

Any help greatly appreciated!

Hey Michael,

Yes, you should hold the button down and use the OLD flasher to flash the NEW bootrom. I know it is kind of an hassle, but you only have to do this ones

Thank btw, for your bug report here, can you check if my patch fixed it?

Cheers,
