hi,

Me and Alan Carvalho de Assis tried nuttx-bb on the calypso and we failed to get any serial or sercomm output.

The setup: ------------ 1) clone the following repository(or add as remote and checkout the correct branch): git://git.osmocom.org/osmocom-bb git://gitorious.org/gnutoo-s-for-upstream-osmocom-bb-and-nuttx-bb/nuttx-bb- gta02.git osmocom-bb and nuttx-bb-gta02 must be in the same directory. nuttx-bb-gta02 has 2 small patches made by me.

One is for fixing compilation. And the other one is the result of a diff between compal_e99's init.c and the gta02's init.c

2) setup the toolchain: we didn't use gnuarm toolchain because it gave that when compiling nuttx-bb: arm-elf-ld: ERROR: /home/gnutoo/temp/osmo/nuttx-bb-gta02/nuttx/../../osmocom- bb/src/target/firmware/comm/libcomm.a(sercomm.o) uses hardware FP, whereas /home/gnutoo/temp/osmo/nuttx-bb-gta02/nuttx/nuttx uses software FP So we tried the arm-2010.09 codesourcey we put it in the path.

3) compile osmocom-bb: cd osmocom-bb/src make clean make cd ../../

3) compile nuttx-bb: cd nuttx-bb-gta02/nuttx cd tools ./configure.sh compal_e99/nsh cd ../ make CROSSDEV="arm-none-eabi-" clean make CROSSDEV="arm-none-eabi-"

that gives a file named nuttx.bin

Then I tried it to load on my om-gta02: scp nuttx.bin root@192.168.7.2: ssh root@192.168.7.2

root@om-gta02:~# /etc/init.d/dbus-1 stop Stopping system message bus: root@om-gta02:~# /etc/init.d/xserver-nodm stop Stopping XServer root@om-gta02:~# osmocon -i 13 -m romload -p /dev/ttySAC0 nuttx.bin and on another console: ssh root@192.168.7.2 root@om-gta02:~# echo 1 > /sys/bus/platform/devices/gta02-pm-gsm.0/download root@om-gta02:~# echo 0 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on root@om-gta02:~# echo 1 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on which results in the following on the first console: [...] Finished, sent 63 blocks in total Received block ack from phone Sending checksum: 0xf6 Checksum on phone side matches, let's branch to your code Branching to 0x00820000 Received branch ack, your code is running now!

but nothing on sercomm. And nothing on IRDA serial port either....

and IRDA serial cable works too: if I do that again: root@om-gta02:~# echo 0 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on root@om-gta02:~# echo 1 >/sys/bus/platform/devices/gta02-pm-gsm.0/power_on I get the default modem software messages on the serial port...

Previously I tried to print on the IRDA serial port with: cons_puts("HELLO WORLD\n\n"); in apps/examples/hello/main.c and of course enabling the hello world application in the apps config. Nothing was printed either....

here's the app config:

CONFIGURED_APPS += examples/hello in apps/.config

And here's the diff for the application: diff --git a/apps/examples/hello/main.c b/apps/examples/hello/main.c index 308603f..db55ac3 100644 --- a/apps/examples/hello/main.c +++ b/apps/examples/hello/main.c @@ -58,7 +58,10 @@

int user_start(int argc, char *argv[]) { - printf("Hello, World!!\n"); - return 0; + while (1){ + cons_puts("HELLO WORLD\n"); + printf("Hello, World!!\n"); + } + return 0; }

Alan Carvalho de Assis tried on features phones and not on the gta02 with the same result...
