GTA01 is the codename of the first phone developed from Openmoko. It was sold under the name Neo 1973. This page gives you an historical overview of which steps were needed before the Neo 1973 was born.
- Neo 1973 (GTA01B_v4)
- Battery (1200mAh)
- Phone Pouch
- SanDisk 512MB MicroSD Card
- Mini USB Connectivity Cable
And as from GTA01Bv1:
- Bluetooth (;
First generation of prototypes that was given to internal OpenMoko software developers.
Unfortunately not useful at all due to non-working touchscreen.
- ATAG_REVISION: 0x0000130
Unfortunately still not useful due to half-working touchscreen.
- ATAG_REVISION: 0x00000140
This is the bluetooth-enabled fork of GTA01
This is the first produced version of the bluetooth-enabled version.
- ATAG_REVISION: 0x00000220
GTA01Bv3 (Phase 0)
This is the second produced version of the bluetooth-enabled version. It contains mainly GPS-related fixes.
- ATAG_REVISION: 0x00000230
PMU unable to resume from suspend
Due to use of wrong GPIO/EINT pin, the PMU cannot wake-up the phone after suspend. This means, specifically, the following events can not bring the phone back from suspend-to-ram:
- PMU RTC Alarm
- Power button press
- Charger events (charger insertion/removal/error)
- Low battery
Stand-by time extremely low
This is due to a design bug resulting in at least 30mA additional standby current, since we cannot properly switch off the power supply to the S3C2410 PLL's. There is nothing we can do to change this with post-production fixes. GTA01Bv4 will address this issue.
GSM doesn't resume phone from suspend
The GSM modem currently doesn't signalize a wakeup interrupt to the S3C2410 in case there's some noteworthy event, such as incoming call, loss of network, incoming SMS or the like.
This is a serious issue, but can be fixed with a GSM Modem Firmware update.
GSM Sidetone too loud
The local feedback sidetone (see ) is too loud. This will be addressed in a GSM firmware update
Due to an error in the production process, the factory-programmed NAND bad block information has been lost. This means that some blocks in the flash will wear out rapidly, which might become as bad as rendering the device unusable.
GTA01Bv4 (Phase 1)
This is the version that is being shipped in Phase 1
- Fix all Errata items from GTA01Bv3
- Add I2C, SPI and one irq and wakeup capable GPIO pin to debug port plus have test pads for all these signals (for soldering wires directly on the pcb)
- Fix a number of production related details and minor hardware details that are not user-visible
Neo 1973 Base -- everything the mobile application developer needs to enjoy the benefits of the first freed phone, the Neo 1973:
* Neo 1973 (GTA01B_v4) * Battery (1200mAh) * Stylus * Headset * Phone Pouch * Lanyard * SanDisk 512MB MicroSD Card * Mini USB Connectivity Cable
Neo 1973 Advanced -- everything the mobile device hacker wants to get down and dirty with the first freed phone, the Neo 1973:
* Neo 1973 (GTA01B_v4) * Battery (1200mAh) (2x) * Stylus * Headset * Phone Pouch * Lanyard * SanDisk 512MB MicroSD Card (2x) * Mini USB Connectivity Cable (2x) * Debug Flex Cable * Debug Board v2 (JTAG and serial console) * Ruggedized Toolbox with shoulder strap * Guitar Pick (for opening case) * Torx T6 screwdriver
This is what the GTA01Bv4 PCB looks like without the shielding cans, which will be fitted later.
There were two versions of GTA01Bv4: some were given away (red mainboard), and some were sold (green mainboard). The given-away have one transistor too many.
