Pirelli DPL10 - nuttx and dump flash for restore later

I followed the steps you mentioned Alan and when loading I do the following:

~/workspace/osmocom-bb/src/host/osmocon$ ./osmocon -p /dev/ttyUSB0 -m romload ../../target/firmware/board/compal_e88/chainload.compalram.bin -c nuttx.bin 
got 2 bytes from modem, data looks like: 3e 69  >i
Received ident ack from phone, sending parameter sequence
read_file(../../target/firmware/board/compal_e88/chainload.compalram.bin): file_size=4378, hdr_len=0, dnload_len=4381
Received parameter ack from phone, starting download
Finished, sent 5 blocks in total
Received branch ack, your code is running now!

Hit Ctrl-C and try minicom, no data or response to input in minicom. No change in screen either.

The load happens very fast so I wonder if it is even really working?

I can load the standard osmocom apps fine.

I never tested it on Pirelli phone, but since it is same baseband as
GTA phones, you just need to use:

$ cd nuttx/tools
$ ./configure.sh compal_e88/nsh_highram
$ cd ..
$ make

Then upload nuttx.bin using chainload.compalram.bin as explained here:


Keep in mind the main development platform for nuttx-bb is C155 (compal_e99).

If you need help, please enter in IRC channel ##nuttx-bb (irc.freenode.net).
