Linux: DM3730 UART3 download x-load.bin problem

Hi user5052928,

Could you specify what kind of DM3730 board you are using? For example if you are using EVM board you should check the switch configuration required for peripheral booting from UART3.
Also check whether the x-loader loading is properly completed as it is described in the linked below tutorial:
projects.goldelico.com/.../

thanks
the kind od DM3730 of mine is omap3evm
configure with ""make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm omap3evm_config""
SYS.BOOT[5:0] = 110111
the sequence is UART3-> MMC2
I follow the ways of elinux.org/BeagleBoardRecovery
and the TI documentation says that the UART3 x-load.bin will be copied to internal SRAM at 0x40200000
so I check the TEXT_BASE and i found that

/* board/omap3evm/config.mk */
# (C) Copyright 2006
# Texas Instruments, <www.ti.com>
#
# OMAP3EVM board uses OMAP3430 (ARM-CortexA8) cpu
# see http://www.ti.com/ for more information on Texas Instruments#
#
# OMAP3EVM has 1 bank of 128MB mPOP-SDRAM on CS0
# Physical Address:
# 8000'0000 (bank0)

# For use if you want X-Loader to relocate from SRAM to DDR
#TEXT_BASE = 0x80e80000

# For XIP in 64K of SRAM or debug (GP device has it all availabe)
# SRAM 40200000-4020FFFF base
# initial stack at 0x4020fffc used in s_init (below xloader).
# The run time stack is (above xloader, 2k below)
# If any globals exist there needs to be room for them also
TEXT_BASE = 0x40200800
PLATFORM_RELFLAGS += -DONE_BIT_ERROR_CORRECT


I have tried and failed to boot the 3730 using 0x40200800,40200000,0x80e80000
but it still doesn't work as well
so i don't know how to do

Could you post the console output to check the pserial and ukermit work?

Hi Tsvetolin Shulevk
the x-load.bin works well when it booting from the emmc.
as long as the x-load.bin works， i can transmit the u-boot.bin successful and uboot start booting .(MLO works at mmc )
when i transmit the x-load.bin successful with the tools of pserial ,i can't tansmit u-boot.bin to the board.
so i think the reason why it can't transmit the u-boot.bin is that the x-load.bin doesn't works.
because once it works ,i can transmit the u-boot.bin successful.



i defined the DEBUG to check whether the pserial works.
# ./pserial -p /dev/ttyUSB1 -f x-load.bin
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs

so please tell me why the x-load.bin doesn't works? it transmit completed.

thanks

Hi Tsvetolin Shulev
I follows the ways of e2e.ti.com/.../2260372
and uboot starts just fine.
thanks
