Hi,
Alan Carvalho de Assis and me have been working on making nuttx-bb work on our phones( I've a gta02 and he has a Motorola W220) and here are the patches(against nuttx-bb).
To try it, clone nuttx-bb and osmocom-bb, put it in the same directory and keep the name of the osmocom-bb directory. Then put the gnuarm(for 64bit) or the codesourcery(for 32bit) in your path(there is a problem with gnuarm for 32bit). Compile osmocom-bb as usual(cd osmocom-bb/src && make). Then go in nuttx-bb directory and do: cd nuttx/tools/ ./configure.sh compal_e88/nsh #for for compal_e88( gta02 and Motorola W220). ./configure.sh compal_e99/nsh #we need testers for compal_e99, we don't have one. cd ../ make
That will create a nuttx.bin, load it as usual(like any other firmware for your calypso). Then the following will appear: Finished, sent 63 blocks in total Received block ack from phone Sending checksum: 0x66 Checksum on phone side matches, let's branch to your code Branching to 0x00820000 Received branch ack, your code is running now!
NuttShell (NSH)
To send commands to the shell you need to run loadwriter.py that is included in the source code at: nuttx/drivers/sercomm/loadwriter.py
The list of commands can be found by typing help.
Denis.

We cannot send a big chunk of bytes to sercomm_puts because .txready on NuttX doesn't detect when "UART" finished sending data, then data are lost. An work-around to fix it is sending less bytes and putting a delay after each transfer.

I could simplify this if/else by:
cnt = buflen & 0x1F;
but I think it will not be readable for other people.

Yes, my fault, it should saturate on 31 if buflen bigger than 31.
So, let us keep this if/else.

The compal_e88 directory contains a fixed linking script to make it work romloader compatibles phones.

Hi Denis,
thansk a lot for your work on the nuttx-bb code base. As there isn't really any other activity in the repository, I'm happy to give you direct git write access. If you'd like that, please send me a SSHv2 public key.

If you'd like to test E99, I can send you guys one or two new C155 for free.
Just let me know the shipping address in private mail.
