Dear all,
Happy Yuanxiao(Lantern) Festival!
I have a modified mx28-evk board, I want to run barebox on it, but I don’t want to make change to the flash.
In System.map
00000000 T __image_start
00000000 T start
00000000 T _stext
00000000 T _text
00000004 T __bare_init_start
00000004 T get_runtime_offset
00000014 t linkadr
00000018 T __ld_var_base
00000018 T __ld_var__text
00000020 t ___text
00000024 T __ld_var___rel_dyn_start
0000002c t ____rel_dyn_start
00000030 T __ld_var___rel_dyn_end
00000038 t ____rel_dyn_end
0000003c T __ld_var___dynsym_start
00000044 t ____dynsym_start
00000048 T __ld_var___dynsym_end
00000050 t ____dynsym_end
00000054 T __ld_var___bss_start
0000005c t ____bss_start
00000060 T __ld_var___bss_stop
00000068 t ____bss_stop
So, I load barebox.bin to address 0x00000000:
Hit any key to stop autoboot: 0
MX28 U-Boot > tftpboot 0 barebox.bin
Using FEC0 device
TFTP from server 192.168.12.61; our IP address is 192.168.12.62
Filename 'barebox.bin'.
Load address: 0x0
Loading: T #############################
done
Bytes transferred = 424776 (67b48 hex)
MX28 U-Boot > go 0
## Starting application at 0x00000000 ...
I believe the sram is too small to load the binary.
So, I change the TEXT_BASE to 0x41600000 in menuconfig, build and update barebox.bin, it print funny characters:
MX28 U-Boot > <INTERRUPT>
MX28 U-Boot > <INTERRUPT>
MX28 U-Boot > tftpboot 0x41600000 barebox.bin
Using FEC0 device

For imx283, How to run barebox from ram?
Thanks,

Which image do you start? It seems you are trying to start barebox.bin.
It should be images/barebox-freescale-mx28evk-2nd.img instead.
The image should be linked to 0x0, that is right. The code is position
independent though and the full barebox relocates itself to the end of
the available SDRAM automatically. TEXT_BASE is not relevant here.

Yes.
Which image do you start? It seems you are trying to start barebox.bin.
> barebox.bin and barebox-freescale-mx28evk-2nd.img
It should be images/barebox-freescale-mx28evk-2nd.img instead.
The image should be linked to 0x0, that is right. The code is position
independent though and the full barebox relocates itself to the end of the
available SDRAM automatically. TEXT_BASE is not relevant here.
The start symbol is still 0x00000000 even I change TEXT_BASE in menuconfig.
my board have 64MiB ram. Modified board.
Very cheap one, just 33€. :D

This board has a LCD(480*800?), I want to test font support on this board.
The sch is here:

There are many pcf fonts here:

and maybe use code from freetype?

You are running on a board which actually is no mx28-evk, so it's no
wonder it doesn't work. Please mention that next time, because that
changes the question from "What is broken with the mx28-evk" to "What is
different on your board". This is a very important detail to answer
questions.
Anyway, you say your board only has 64MiB of RAM, so you must at least
change:
ENTRY_FUNCTION(start_barebox_freescale_mx28evk, r0, r1, r2)
{
barebox_arm_entry(IMX_MEMORY_BASE, SZ_128M, NULL);
}
to SZ_64M. Other differences might include the pinmux and the UART port
number which is used for console output.

You are running on a board which actually is no mx28-evk, so it's no wonder
it doesn't work. Please mention that next time, because that changes the
question from "What is broken with the mx28-evk" to "What is different on
your board". This is a very important detail to answer questions.
Anyway, you say your board only has 64MiB of RAM, so you must at least
change:
ENTRY_FUNCTION(start_barebox_freescale_mx28evk, r0, r1, r2) {
barebox_arm_entry(IMX_MEMORY_BASE, SZ_128M, NULL); }
to SZ_64M. Other differences might include the pinmux and the UART port
number which is used for console output.
