Issue with C139

Hi all,

I have been using C123 for a long time with FTDI cable.
I recently bought a C139 on which I wanted to run layer1 fw, i check the SW
version using #02# and software version is "1.3.29", UART Flag  is "0"
On going through the mailing list I found these to be sufficient for using
osmocom-bb but some how there is a problem on loading.

When I use the fwg command
./osmocon -p /dev/ttyUSB0 -m c140 -c
../../target/firmware/board/compal_e86/layer1.highram.bin

I get the following
got 2 bytes from modem, data looks like: 04 81  ..
got 5 bytes from modem, data looks like: 1b f6 02 00 41  ....A
got 1 bytes from modem, data looks like: 01  .

Received PROMPT2 from phone, starting download
handle_write(): 4096 bytes (4096/15341)
handle_write(): 4096 bytes (8192/15341)
handle_write(): 4096 bytes (12288/15341)
handle_write(): 3053 bytes (15341/15341)
handle_write(): finished

It receives prompt2 and loads the file but doesn't move ahead, the phone
does not show layer1 on the screen either.

when i use fwg command (add -m c140xor )

./osmocon -p /dev/ttyUSB0 -m c140xor -c
../../target/firmware/board/compal_e86/layer1.highram.bin

I get the fwg:

It now move ahead and says the received MAGIC NACK and also that you need
to have "1003" at 0x803ce0, this is a documented problem and i believe in
compal_e86 binaries must have been taken care of.

Any ideas on how can I get around this and load the firmware on my c139 ? I
am again usung the same cable FTDI which works perfectly with c123.
My setup is native Ubuntu 14.04 , host machine and Intel i5.. (hw does not
seem to be the problem)

Looking forward to hear from you guys. Thanks in advance.

Regards,

Ajay
