Hi all,

I'm new on this mailing list.

Yesturday, I tried to upgrade my GSM firmware. I strictly followed to
wiki https://wiki.openmoko.org/wiki/GSM/Flashing

After loadinf FLUID everything were fine ... I started again the
module by typing 's3c24xx-gpio b7=1' as said in the wiki, and it
started to flash the firmware. While it was flashing (I could see the
progress ...) It failed by a 'Flash operation timeout'error

Now, the GSM module seems to not respond anymore :'(

If I retry, I get :

root at om-gta02:/usr/sbin# FLUID_PORT=/dev/ttySAC0 FLUID_FLOWCONTROL=h fluid.exe \
> -oO -b 115200 \
> -f $HOME/gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-moko10.m0
FLUID Revision 2.27, (23 Aug 2004). Copyright Texas Instruments, 2001-2004.
Reading image file:
(2138kB) ok

But nothing append even if I start the module by typing in another
terminal 's3c24xx-gpio b7=1'


root at om-gta02:~# cat /dev/ttySAC0 &
root at om-gta02:~# echo -en 'AT\r' >/dev/ttySAC0
root at om-gta02:~# echo -en 'AT+CGMR\r' >/dev/ttySAC0

does not say anything ...

Can somebody please help me ?
