07 Sep 2011

• first phone calls
• USB-OTG problems solved

20 Aug 2011

• 5 boards completed with DM3730 and UMTS module and mostly working
• Presentation by Mickey Lauer at FrOSCon

25 Jul 2011

• first board completed with DM3730 and UMTS module
• CPU and some peripherals are working
• UMTS is working

16 Jun 2011

• first two GTA04A3 board received from production (complete except UMTS module)
• now fixing initialization software and testing everything
• first result: 1 board boots; 1 does not

31 May 2011

• CPU chips (DM3730CBP) arrived

20 Apr 2011

• still waiting for PCBs and CPUs to arrive for SMD production
• we have patched the GTA04A2 board so that it boots Linux (LXDE/Debian) - see Video 3

23 Mar 2011

• memory chips arrived (MT29C4G96MAZAPCJG = 512 MByte RAM, 512 MByte NAND flash)
• new PCB layout for the GTA04A3 done

25 Feb 2011

• we have discussed and shown the GTA04A2 during FOSDEM 2011
• some components for the Early Adopter units have arrived (e.g. UMTS modules); others are missing but ordered (Memory, CPU)
• we are completely reworking the layout to (fundamentally) solve the power supply issues and to reduce risk of buzz, noise and other radio interference problems

19 Jan 2011

• first engineering sample (GTA04A2) is working in PDA mode (U-Boot in NAND Flash) - see Video 1 and Video 2
• has some issues in power supply to be fixed in GTA04A3

Well, the project started in May 2008 but too many details to report.
