Hi all,
Neither the 12.3 and 13.1 image boot on Pandaboard-ES Rev B3 because the Modification of Elpida DDR2 RAM
Here follows the serial port messages: U-Boot SPL 2013.04 (Jan 08 2014 - 14:33:37) OMAP4460 ES1.1 SDRAM: identified size not same as expected size identified: 0 expected: 40000000
It seems to be a known problem. See: http://eewiki.net/display/linuxonarm/PandaBoard#PandaBoard-FAQ
Not sure how it will affect other board revision if we rebuild u-boot without CONFIG_SYS_EMIF_PRECALCULATED_TIMING_REGS.
And why upstream u-boot keep things like that if it is known to be broken?
Could we convert this into a runtime check against some easily accessible version register? Alex
