[U-Boot] [RFC] CDC Ethernet support + USB Gadget in U-boot
by Remy Bohmer 19 Jan '12

19 Jan '12

Hello All, We (Thomas Smits and I) have been working on CDC Ethernet support in U-boot. We ported the Linux Gadget and CDC Ethernet driver to U-boot and added support for the Atmel AT91SAM9261-EK kit. Support for other cores can be added easily. Although it is still work in progress, it is already working stable. I also have a patch for adding RNDIS support on top of this series, but that is not finished/stable yet. The series is quite huge, and still in development, so I decided to not post this series inline. I made the tree public via the U-boot-usb tree, 'cdc' branch ( http://git.denx.de/?p=u-boot/u-boot-usb.git;a=shortlog;h=refs/heads/cdc) I would like to stabilise this code in a separate branch until it is mature enough for mainline integration, I will keep this branch always ahead mainline. So, any comments on this code are welcome! But, even more welcome are patches on top of it to make it even better and add more board support for it. Kind Regards, Remy

[U-Boot] [RFC] Add 'led' command
by Jason Kridner 14 Dec '11

14 Dec '11

It is desired to have the led command on the BeagleBoard to allow for some interaction in the scripts. This patch allows any board implementing the coloured LED API to control the LEDs from the console. led [green | yellow | red | all ] [ on | off ] or led [ 1 | 2 | 3 | all ] [ on | off ] Adds configuration item CONFIG_CMD_LED enabling the command.

[U-Boot] P2020 L2 cache as SRAM
by Fabian Cenedese 19 Oct '11

19 Oct '11

Hi We're trying to configure the PPC P2020 cpu to use the L2 cache as SRAM so we can load the U-Boot code in there. However we stumble into problems. Sometimes the cpu goes on trap when trying to access this area. Sometimes there's no trap but we seem to access a different area. That's probably a problem with setting up a TLB/LAW. Has anybody already done this and could share some code with us? I've seen that there's a mpc85xx branch with quite some work going on. Where should we base our work on? Should we use the master or is it better to use this branch? I'm used to svn, not git, so there may be other options I don't know about yet. Thanks bye Fabi

[U-Boot] [PATCH] STx AMC8548: initial support for Silicon Turnkey Express AMC8548 board
by Alex Dubov 18 Oct '11

18 Oct '11

AMC8548 is a RapidIO development board in AMC form factor, featuring MPC8548E processor, DDR2 SO-DIMM slot, 16MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled. Additional board information is available at: http://www.silicontkx.com/AMC8548.htm Signed-off-by: Alex Dubov <oakad(a)yahoo.com> --- This is really a patch repost from Fall, 2009. The board is old and never was that good, but I still got those running, so I propped up an u-boot config as well. Nothing fancy here, just a fairly standard config.

De : PHINEO - ABESSOLO, Gaetan Envoyé : mercredi 1 décembre 2010 10:54 À : 'u-boot-users(a)lists.sourceforge.net' Cc : RADA, KAMAL Objet : u-boot SquashFS HI, I am looking for a u-boot that handles SquashFS filesystem ? Did it exist ? if not can I have some indication or recommendation Because I want to try to upgrade u-boot such that it handles SquashFS Regards Gaëtan ABESSOLO Développement des Systèmes Embarqués (DSE) Département Développement des Produits Fixes (DPF) Bouygues Télécom - Technopôle B1-29 Fixe: +33181751379 Mobile: +33616065864 gabessol(a)bouyguestelecom.fr<mailto:LMARCHEL@bouyguestelecom.fr> ________________________________ L'intégrité de ce message n'étant pas assurée sur internet, la société expéditrice ne peut être tenue responsable de son contenu ni de ses pièces jointes.

[U-Boot] Uboot for Mips
by Rahanesh 13 Sep '11

Hi All, I am currently working on MIPS board. I have a 32MB RAM. The address that is shown in uboot when i type bdinfo if 0x80000000 and size is 0x1000000(16MB). I want to increase the size to 32 MB as board has 32 MB RAM. Interesting Finding: When i write any data to 0x80000000 the same data is being written into 0x81000000. Same for all address in the range (data in 0x80000000 - 0x80ffffff is same as 0x81000000 - 0x81ffffff ). It seems that there is a dual mapping . What might be the reason?
