Subject: barebox on beagleboard: two questions
Date: Sun, 20 Dec 2009 11:13:39 -0500 (EST) [thread overview]
Message-ID: <alpine.LFD.2.00.0912201108280.22419@localhost> (raw)
one question almost certainly dumb, the second maybe not so much.
first, using the current git pull, i:
$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux- (using ELDK toolchain)
$ make omap3530_beagle_per_uart_defconfig
$ make
eventually, copy generated "barebox.bin" to MMC/SD as u-boot.bin, and
boot beagle:
Texas Instruments X-Loader 1.4.2 (Feb 19 2009 - 12:01:24)
Reading boot sector
Loading u-boot.bin from mmc
barebox 2.0.0-rc10-dirty (Dec 20 2009 - 03:21:55)
Board: Texas Instrument's Beagle
Malloc space: 0x87bfff10 -> 0x87ffff10 (size 4 MB)
Stack space : 0x87bf7f10 -> 0x87bfff10 (size 32 kB)
running /env/bin/init...
not found
rday> [different prompt just to prove new image}
at that point, every single command i type gives me "Unknown
command", which may be because i haven't read all the docs and have
done nothing in terms of an environment. i figured it was just worth
doing the trivially obvious to see what happened.
not so trivial -- board/omap/board-beagle.c:
...
/**
* @brief Do the SDRC initialization for 128Meg Micron DDR for CS0
*
...
static struct device_d sdram_dev = {
.name = "mem",
.map_base = 0x80000000,
.size = 128 * 1024 * 1024,
.platform_data = &sram_pdata,
};
...
all the newer beagles have 256M of RAM, not 128M. does this mean my
board is being initialized improperly? or should i be reading the
above differently?
