Q2687RD firmware 7.52 upgrade by XMODEM problem

Postby kamil_belter » Wed Apr 19, 2017 1:24 pm

Hi,

I've tried to upgrade firmware from 7.45 to 7.52 by XMODEM-1K. Bootloader was correctly updated, but firmware update is failing. For update I'm using custom application with XMODEM-1K protocol implemented. Q2687RD cancels XMODEM-1K transmission (by CAN) after receiving ~70% of file (938 or 939 packet; packet size is 1024) and few times during firmware update application received char stream out of XMODEM-1K protocol with content:
*** XMODEM BINALLOCATION ERROR ***

I've checked that firmware 7.46 and 7.51 upgrades correctly.

I would appreciate your help in this topic.

Hi,

I've found solution. There was similar problem with SL6087 mentioned in this topic: viewtopic.php?f=118&t=10238

Using WOPEN=4 command to erase the binary from memory helped with upgrade.
So my procedure was (I had firmware 7.51 installed):

1. update botloader
2. restart modem
3. check if modem response with AT
4. WOPEN=4
5. check if modem response with AT
6. "AT+WDWL"
7. send file with XMODEM
