| 1 # Openmoko's GTA01/02 modem design is based on earlier Calypso phone or modem | |
| 2 # designs by FIC, going back to 2004 according to dated comments in OM's FLUID | |
| 3 # devices.txt file, and that parent design originally supported bigger flash | |
| 4 # chips than the ones used in mass-produced GTA01/02 units. The latter have | |
| 5 # Samsung K5A3240CTM or K5A3281CTM chips populated in them (4 MiB of flash, | |
| 6 # 512 KiB or 1 MiB of RAM), but the PCB footprint actually fits a 16 MiB flash | |
| 7 # chip (Spansion S71PL129J), with the second flash chip select wired to Calypso | |
| 8 # nCS4. That devices.txt file also indicates that this nCS4 wiring was used | |
| 9 # in FIC's 2004 design as well. | |
| 10 # | |
| 11 # This loadtool config is set up to address this maximum possibility of 16 MiB | |
| 12 # of flash (in this particular wiring) or any subset thereof; it may be needed | |
| 13 # if some early GTA01 prototype devices still had the bigger flash in them or | |
| 14 # if someone finds an earlier (pre-Openmoko) FIC phone or modem. | |
