Hi,
I'm pretty new to u-boot and I am trying to use it on the mx28 platform.
I have an MX28 EVK (rev A), which I'm using. I was able to build u-boot
2009 with all the patches supplied by Freescale, and to get it working.
I moved on to u-boot 2011 because I wanted to use the I2C, SPI and other
tools supported.
The problem I have is that when I build u-boot, it hangs at after
dram_init during the initialization sequence.
This is what I get from u-boot...
PowerPrep start initialize power...
Battery Voltage = 4.26V
boot from battery. 5v input not detected

finish simple test
U-Boot 2011.12 (Apr 04 2012 - 16:55:47)
Freescale i.MX28 family
I2C: ready
DRAM: 0 Bytes
I realize this problem was supposed to have been fixed by several
patches, but it still exists.
On my platform it seems to occur if SPL is configured, and during
relocation.
U-boot is not able to get the proper RAM size from the scratch registers
(SCRATCH0, and SCRATCH1).
I've even tried the latest u-boot (2012.04.rc1) and I still get the same
results.
Can anyone help me or point me in the right direction?
Thanks.
Chiz
