IndexError: index out of range

Thanks for creating and publishing this project, I tried using it to flash multiple FW to a zigate and am getting the following error:

./zigate-flasher.py -p /dev/ttyUSB1 -w ../ZiGate_Coordinator_v3.0e.bin -e
Found MAC-address: 00:15:8d:00:01:b2:2a:54

I don't get this error when using JennicModuleProgrammer.

Same problem here:

Looks like it is related to the use of Erase option

@tjikkun do you have any idea on how to fix this issue ? Basically I'm not able to Erase EEPROM nor PDM

[tjikkun]

@doudz wrote this part (erase option). I haven't played with Zigate for a while now so have not really tested that part myself.
From what I remember this was not a documented feature of the bootloader. If I recall correctly JennicModuleProgrammer uses a boot image that it boots from, which then erases the EEPROM from within that boot.

Hello. I am struggleling with my ZiGate update witch lead me to zigate-flasher.
As far as I understand, both JennicModuleProgrammer and zigate-flasher erase the FLASH memory with command 0x07 before writing the new firmware.
zigate-flasher implements an undocumented (and apparently not functional) command 0x36 to erase EEPROM. Dont know what we are supposed to achieve with that.

[pipiche38]

My understand is that the command 0x07 is an Erase in preparation of the flash ( this is done by JeenicModuleProgrammer as well as the zigate-flasher), the 0x37 is done after the flash to Erase the EEPROM

[chrisaga]

Yes, I think this is the idea. Unfortunately, erasing the EEPROM doesn't work.
I needed it and I managed to run the windows utility under wine to achieve that. I have no access to the sources nor to debuging tools so I don't know how it's done.

2 years ago I started to port NXP programmer to Python3, it's not working but it can help
