Hi, Thanks a lot for your info, but my board still can't work with binary file building with mainstone patch. My board's info as following: 1 CPU: PXA270 2 SDRAM :0xA0000000 - 0xA4000000 64M 3 BOOT: nCS<0> CODE: 0x00000000 4 FFUART: GPIO34?FFRXD GPIO35?FFCTS GPIO36?FFDCD GPIO37?FFDSR GPIO38?FFRI GPIO39?FFTXD GPIO40?FFDTR GPIO41?FFRTS As I'm a newer to uboot and PXA270, so in my opine, after patched the uboot114 directory, I just need to modify the mainstone.h to fit my board. But I failed. Then after compared with start.S for other cpus such as ixp, I found that the reset code are very similar to each other. At first I doubted about the reset code, so I modified start.S and lowlevel_Init.S with the start code of blob. But I failed yet. Could you possible give me some suggestion? Thank you very much.Best regardsJohn > Date: Wed, 16 May 2007 18:18:30 +0200> From: hbmeier at uni-paderborn.de> To: arm.linux at koansoftware.com> CC: bdx_1981 at hotmail.com; u-boot-users at lists.sourceforge.net> Subject: Re: [U-Boot-Users] u-boot for PXA270> > Marco Cavallini schrieb:> > John ha scritto:> > > >> Dear all,> >> I am John , and I met a problem about uboot migrate for PXA270.> >> My modification as following:> >> 1 add my board johnPxa in Makefile> >> johnPxa_config : unconfig> >> @$(MKCONFIG) $(@:_config=) arm pxa270 johnPxa> >> 2 add my board directory under board/ with board/lubbock> >> cp -a lubbock johnPxa> >> 3 add johnPxa.h under include/configs/ with lubbock.h> >> cp lubbock.h johnPxa.h> >> and modified it as my board's configuration.> >> 4 add pxa270 directory under cpu/ with cpu/pxa> >> cp -a pxa pxa270> >> 5 modified config.mk under cpu/pxa270/> >> PLATFORM_CPPFLAGS += -mapcs-32 -march=armv5 -mtune=xscale> >> 6 add my board information into mach-types.h> >> 7 modified start.S(cpu/pxa270) with blob's start.S and> >> xlli_LowLev_Init.s> >> ps: this blob could run on my board.> >> and I compiled with arm-linux-gcc 3.4.1> >> At last the u-boot.bin couldn't run on my board.> >> Could you give me some help, thank you very much.> >> Best regards> >> John> >>> >> _________________________________________________________________> >> > >> > FYI> >> > Here you can find some already done work:> > http://www.koansoftware.com/en/prd_svil_projects.htm> >> > u-boot bootloader patch for Intel Mainstone> > (aka HCDDBBVA0) with ethernet support> > patched against 1.1.4 cvs> >> > Other resources are here:> > http://pxa-linux.sourceforge.net> >> > HTH> > > Hi,> > U-Boot already support PXA270.
