i am experiencing a strange problem programming a parallel flash memory SST29VF3201B (2Mega x 16bit words) from a coldfire processor.
i try to explain what happen
1) using the constructor programming algorithm, i erase the flash, this succeded, i have all the 16bit words to 0xFFFF...
i have developed a little custom board, with a MCF5307, a 16x2MB (word programmable) parallel flash (SST39VF3201B), a 16MegB. SDRAM and some other peripheral.
Anyway, since this is one of my first quite big embedded circuit development, i connected for error the flash memory address...
i get a sim300_dev board, and i would be able to send some sms.
After startup i get:
+CPIN: NOT INSERTED
I trying to put a pin, with AT+CPIN i get +CME ERROR: 10
if some help,
