Revision
Notable Changes
B
Initial release of the board
C
1. Fixed the VGA problem with development edition;
2. changed UART1 to UART0 and added new UART1;
3. added SMD jumper to be able to disable CS if you wish to boot from SD

4. JTAG signals are on led to pads;
5. added test pads for the voltage of all regulators;
6. moved couple of elements for better distance between each other
D
1. Removed resistor matrices, except the ones near DDR3 memories – to
lower fault rates
2. Added header NA(HN1X2) so you can power only the RTC from external
battery
3. BAT54C is added to allow RTC powering either from VDD_RTC or 3.0V_BAT
E
1. Added BAT54C after Rx to UART1 connector
2. Added 100k pull-up resistor on the RX line
3. Changed wrong prints of the revision and the Olimex web-site
4. Some libraries updated and some component prints removed due to space
