[U-Boot-Users] helloworld app from flash?
by Ram 08 Sep '07

08 Sep '07

Hi, im trying to run the helloworld application 1st Option: download the hello_world.bin to some location on RAM and execute it OMAP5912OSK: tftpboot 0x10000000 hello_world.bin OMAP5912OSK: go 0x10000004 This works fine. no problem 2nd Option: I want to burn the hello_world.bin into flash. During startup i want u-boot to launch it after booting - just like the way it boots the kernel. It does not work for me, this is what i did. $ ../tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10000000 -e 0x10000004 -n 'Hello Image' -d hello_world.bin.gz hello.img I downloaded the hello.img and burnt it to 0x40000 I did: setenv bootcmd bootm 0x40000 Now when i restarted the boot i get the following:- Example expects ABI version 2 Actual U-Boot ABI version 2 Hello World argc = 0 data abort pc : [<10000058>] lr : [<10000048>] sp : 1103fc10 ip : ffffffff fp : 00000001 r10: 110996d8 r9 : 1103fca4 r8 : 1103ffdc r7 : 110996d8 r6 : 00000203 r5 : 00000000 r4 : 00000000 r3 : 00000020 r2 : 00000001 r1 : 0000000a r0 : 00000000 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... All i am doing in the hello world example is to read a line and print the line entered. I am using readline function for doing that. The programs works fine if i download it to RAM and say go. but if i flash it it does not work?. Am i missing something?. Regards, sriram

[U-Boot-Users] [PATCH 1/1] Support for National DP83848 Ethernet Phy
by kim M 22 May '07

22 May '07

Hi all If anyone interested, this is a patch which adds support for the National DP83848 Ethernet Phy. It allows derivatives of the at91rm9200dk board to use this Phy. You will have to edit your at91rm9200.c to use this Phy instead of the default dm9161. I think it makes sense to include it in the main branch, since it is a free feature and it does not occupy space unless used. BR Kim

[U-Boot-Users] [PATCH] simplify silent console
by Ladislav Michl 24 Apr '07

24 Apr '07

Wolfgang, silent console output is currently implemented by assigning nulldev as output device. This is a bit overcomplicated, since there is also GD_FLG_SILENT flag. Patch bellow tries to simplify silencing console by honouring GD_FLG_SILENT in console output functions, so there is no need to mess with output device. Comments?

[U-Boot-Users] Sequence of Xilinx ML403/PPC
by S. Egbert 28 Dec '06

28 Dec '06

Awesome... Got U-boot 1.1.4 working on a Xilinx ML403 (PPC 405) evaluation board with our custom core. Next for this planning stage, I'm trying to juggle 'leap-frogging' memory mapping between the first-loader (Xilinx SREC bootloader in firmware), second loader (U-boot 1.1.4) and Linux 2.4 OS. Firstly, we started with Xilinx's SREC (bootloader.c) bootloader (I know, I know, SREC is space consuming) and plan to replace this first bootloader with an ELF or pseudo-binary version later after everything-else is checked out. Planning-wise, I envisioned that such a bring-up memory overlaying sequence would be something like this: 1. Xilinx bootloader.c reads SREC from 16-bit flash and decode/verify/copies to lowest RAM (0000_0000). Then transfers control to 0000_0100. 2. U-boot starts up and relocate itself to MONITOR region which is in the highest RAM region of 01F0_0000. 3. U-boot Scripting occurs which copies Linux OS from flash into where? Next highest or lowest portion of RAM? Is it dependent on whether dual-stage vmlinux.initrd or single-stage vmlinux is used or not? At power-up, with U-Boot 1.1.4 being unusually low-RAM-based before starting up (instead of executing straight out of ROM), I noticed that despite being relocated to MONITOR (higher RAM) region, the PIT exception vector appears to be active in 0000_10c0-ish. Despite this RAM-to-RAM relocation, this "mtest" clobbering of the 0000_10C0 region caused Machine Exception error whenever I attempt to perform memory test over this supposedly former exception vector region. I thought that the objective during U-boot relocation was to ensure a completely discontinued RAM region (formerly occupied by U-boot ROM-based session). A hard and easy questions to the esteemed and avid readers of u-boot-users mailing list... 1. Where do I go from there with regard to the 0000_1000 (PIT_EXCEPTION). Isn't the PIT specific to Motorola 8xx-series (this here is a PPC 405). What exception did the lib_ppc/start.S/trap_init() exactly skipped? Skipped an exception mentioned vaguely in this source code vaguely. Do I need to tweak the trap_init() some more to relocate these untransfered exception vectors into the high MONITOR region? 2. And lastly, do I go high or low for Linux OS? Thank you, S. Egbert

G'Day, Has anyone given PXA27X USB support a go? If not, I'm probably going to need to have a crack. Anyone else have a need for it? Any sage words of advice from someone who's looked at USB for another platform? Cheers, Dave.
