主要元件
处理器
Neo1973的主处理器(CPU)是一个Samsung S3C2410AL-26 (可运行在266 MHz)

- GPIO分配: https://svn.openmoko.org/trunk/doc/hardware/GTA01Bv3/gpio.txt
闪存
与S3C2410 NAND控制器相连的64MB Samsung NAND闪存(K9F1208U0B)。

- 数据手册: ds_k9f1208x0b_rev03.pdf
- 被连接到: S3C2410 NAND控制器
This is the only flash memory in the device. The S3C2410 boots directly from nand, using the S3C2410 Steppingstone.
We only use free software, no proprietary flash file systems. For a full description of how it is used, see NAND bad blocks
内存
与S3C2410 SDRAM控制器相连的128MB SDRAM (2片Samsung K4M511633C)

GSM/GPRS
The GSM/GPRS modem is Texas Instruments Calypso based.
- Connected to: S3C2410 UART1 (full-uart, RxD, TxD, CTS, RTS), /dev/ttySAC0 in userspace
- PM Driver: https://svn.openmoko.org/trunk/src/target/kernel/patches/gta01-power_control.patch
- Accessible GSM/GPRS antenna jack (if battery cover is removed)
CALYPSO digital baseband
Unfortunately we cannot provide many details on the GSM chipset due to very tight NDAs. However, this is not neccessarily required, since it interfaces using a standard UART serial line with the S3C2410. On that interface, GSM 07.05, GSM 07.10 and other standardized protocols are used.
-- xkr47: Could we at least know the GPRS capabilitiy class and the GPRS multislot class ?

History
GTA01
This is the most simple, non-bluetooth version of the prototype.
GTA01v3
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
GTA01v4
Second generation of prototypes that was given to Harald + Mickey.
Unfortunately still not useful due to half-working touchscreen.
- ATAG_REVISION: 0x00000140
GTA01B
This is the bluetooth-enabled fork of GTA01
GTA01Bv2
This is the first produced version of the bluetooth-enabled version.
- ATAG_REVISION: 0x00000220
GTA01Bv3
This is the second produced version of the bluetooth-enabled version. It contains mainly GPS-related fixes.
- ATAG_REVISION: 0x00000230
This is the version that is shipped in Phase 0
GTA01Bv3 Errata
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 [1]) is too loud. This will be addressed in a GSM firmware update
Bad block
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
This is the version that will be shipped in Phase 1
Changes from GTA01Bv3
- 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
Distinguishing hardware revisions
Inside the Bootloader
Every hardware revision has its own u-boot image type. Thus, the bootloader has the revision hard-coded. The hardware revision is passed on to the kernel via the ATAG mechanism (ATAG_REVISION)
Inside the Kernel
The kernel receives the ATAG_REVISION during bootup, and saves its contents in the "system_rev" global variable.
From Userspace
The kernel exports the system_rev variable in /proc/cpuinfo as "Revision :" line.
