not getting history data off device

[Commander1024]

Ohai,

I bought myself a GMC 320 Plus (GMC-320Re 4.53). Most of this tools function work on this device and give reasonable output like -i, -o, -O, -G, -T and --heartbeat etc.

But it seems like it cannot get the history:

python2 ./gq-gmc-control.py -p /dev/ttyUSB0 -d device found: GMC-320Re 4.53 storing data to '/tmp/tmpTFmCQ4.bin' address: 0x000000, size: 4096, total size: 1 bytes (0%) address: 0x001000, size: 4096, total size: 2 bytes (0%) address: 0x002000, size: 4096, total size: 3 bytes (0%) address: 0x003000, size: 4096, total size: 4 bytes (0%)

This run won't finish (within a reasonable time).

resulting .bin file looks pretty empty:

hexdump gq-gmc-log.bin
0000000 0055 0000 ff00 ffff ffff ffff ffff ffff 0000010 ffff ffff ffff ffff ffff ffff ffff ffff * 0000080 ff55 ffff ffff ffff ffff ffff ffff ffff 0000090 ffff ffff ffff ffff ffff ffff ffff ffff * 00001f0 ffff ffff 00ff
00001f5

Is there any additional info I can provide for debugging?
