Hi Does u-boot support any evaluation boards based on the MPC8548 processor ? Thanks in advance -- Rupesh S

[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

Hi, My hardware has an sd/mmc card. I need to write a few tests to check if the card is connected and working before loading linux. any ideas how one should go abt it?. are there any basic tests for mmc card?. any pointers?. Regards, Jo

[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

[U-Boot-Users] PXA27x USB support?
by David Snowdon 21 Nov '06

21 Nov '06

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.

[U-Boot-Users] MPC8270/MPC8250 Ethernet Problem
by Aaron Sells 07 Nov '06

07 Nov '06

I am having trouble getting Ethernet to work correctly on our Embedded Planet EP82xxM board. Specifically, pings and TFTP transfers fail when the board is populated with an MPC8250 or an MPC8270. However, when the board is populated with an MPC8280 processor, Ethernet works. Any suggestions of things to try out to resolve this would be greatly appreciated. FCC2/3 port pins appear to be correctly configured. PHY registers are able to be accessed and seem to show the correct configuration. No packets are appearing on the wire when sniffed with Ethereal. With ET_DEBUG turned on, pinging results in the following output: ep82xxm=> ping 10.0.0.26 Using FCC3 ETHERNET device sending ARP for 0a00001a ARP broadcast 1 packet received packet received Receive from protocol 0x0 packet received packet received Receive from protocol 0x0 . . .

[U-Boot-Users] mtdparts
by Ladislav Michl 29 Oct '06

29 Oct '06

Hi there. I'm just trying to sync with U-Boot development and found a little regresion in new mtdparts code. Previously I was using custom partition function, which let me do precisely what I wanted. mtd0 - U-Boot mtd1 - env mtd2 - r_env mtd3 - rootfs0 mtd4 - rootfs1 ... etc In above scheme my custom part function allowed only chpart [34], so it was not even possible to change partition to evn sector for example. Moreover it was pretty easy to construct kernel command line this way: setenv bootargs '$bootargs root=/dev/mtdblock$partition ro rootfstype=jffs2' And everything worked nicely. That is no longer case and it's real pain with both NOR and NAND devices used in system. Prefered solution for me is to fix kernel to be able to mount root filesystem from MTD device given by name (root=mtd:rootfs0) unless someone has better idea :-). Something which would work also with 2.4 kernels would be appreciated. ladis
