5" LCD resolution 800x480 working for EOMA. Details here http://www.gplsquared.com/eoma_boot/eoma_boot.html#eoma_with_5inch_lcd These displays are about $16 from Aliexpress: http://www.aliexpress.com/item/5inch-5-TFT-LCD-LCM-RGB-800-480-Display-TOUCH...
I still notice a problem with color - Red and Blue appear to be swapped.
ok. the specification's going to have to change. we cannot modify the CPU Card, so the spec has to be changed to match the card. what a pain.
Hmmmppp...... The is another outstanding issue that needs resolving before the next batch goes into production - this time to do with the RS232 RX line. When connected, the entire board is able to power up through the RX line. The cubieboard1,2 and iteaduino plus and EOMA-A20 boards all have same defect because I assume all of them were designed and tested by the same engineering team from Wits with no peer review input onto the process.
The cubieboard1,2 are not designed by wits. All the allwinner boards including wits are following the allwinner reference design.
Hmm.. MK802 also infected - so I guess everyone is infected.
yes. and the iMX6 is also damageable, and a hell of a lot of other SoCs.
I put up suggestion for UART-RX repair - EOMAs and boards where internal 3.3V is accessible: http://www.gplsquared.com/eoma_boot/eoma_boot.html#uart_repair
oo - magic: a circuit diagram. joe if it's ok i'm going to add that image to the elinux.org wiki ok?
