this board is based on an i.MX25 from Freescale. It consists of a SOM containing :
- NAND flash (internal or external boot supported and tested)
- mDDR (64MB tested)
- ethernet PHY connected in RMII mode (tested)
and a baseboard containing :
- a serial transceiver on UART1 (tested)
- a SDCard connector on eSDHC1 (tested but disabled until Benoît's fix gets applied)
bootlog : U-Boot 2012.10-rc1-00003-gdd12be5 (Sep 23 2012 - 13:53:21)
CPU: Freescale i.MX25 rev1.2 at 399 MHz Reset cause: POR
DRAM: 64 MiB NAND: 256 MiB MMC: In: serial Out: serial Err: serial Net: FEC Hit any key to stop autoboot: 0
Signed-off-by: Eric Bénarderic@eukrea.com
v2: rebased against 2012.10-rc1, disabled eSDHC until proper fix from Benoît gets applied, updated bootlog.
