Freescale I.MX233 Embedded Linux System
Status
Currently not working due to issues with DRAM not seeming to be stable. Might have to mess with the timings a good bit more as well as lowering the clock from 133 Mhz to 100 Mhz.
A 22 uF capacitor under the SDHC holder is too tall, causing the SD card to not fully sit in the holder since it can't be closed, so a finger has to be used by pushing the sd card down when in operation.
NOTE Don't bother with the BCB (Boot Control Block) method of booting. It seems that as per the errta, it is bugged for large SD cards (2GB+). To enable booting via normal partitions on the SD card the board has to be booted into recovery mode and opened on the desktop through the bitburner/OTP burner program. Then burn the OTP bits to enable MBR based booting, if you don't burn them then the MCU will always look for a BCB instead of using the MBR.
