[U-Boot] [PATCH v2] Fix DM9000 MAC address handling
by Ben Warren 22 Oct '09

22 Oct '09

Proper behavior is to pull MAC address from NVRAM in the initialization() an stuff it in dev->address, then program the device from dev->address in the init() function.

[U-Boot] [UBOOT] MUSB: query
by Gupta, Ajay Kumar 22 Oct '09

22 Oct '09

Hi, I don't see MUSB support in uboot for OMAP3 platforms though a few patches supporting MUSB are available in Sakoman's tree (omap-dev-usb branch) since Feb-09. What is the current status on this? I saw some long discussion on MUSB Patches specially for clock changes. Is someone working on this and planning to push those patches to Denx's tree? If not then I would be sending the refreshed patches for OMAP3EVM. Regards, Ajay

[U-Boot] [u-boot] [PATCH] [2/2] [v1.3] mxc_fec: avoid free() calls to already freed pointers.
by javier Martin 22 Oct '09

22 Oct '09

Sometimes, inside NetLoop, eth_halt() is called before eth_init() has been called. This is harmless except for free() calls to pointers which have not been allocated yet. This patch adds two states to distinguish when it is necessary to call free() and when it is not. This has been tested in i.MX27 Litekit board with eldk-4.2 toolchains.

[U-Boot] Write operation for USB storage
by Prafulla Wadaskar 22 Oct '09

22 Oct '09

Hi List I can use fatload or ext2load to read from USB storage My need is to write to a storage over USB interface. With reference to this link https://lists.one-eyed-alien.net/pipermail/usb-storage/2008-May/003665.html Is there any interface available or under development in U-boot to write on USB storage device either raw or through some file system? Regards.. Prafulla . .

[U-Boot] return value from do_ext2load
by David Collier 22 Oct '09

22 Oct '09

the do_ext2load procedure returns the file length if it succeeds... which means you can't do #define CONFIG_BOOTCOMMAND "mmcinit && ext2load mmc 0:1 0x10400000 /boot/uImage && bootm 0x10400000" Is this part of some vast eternal plan and/or can anyone see a way to make it function as desired anyway?

[U-Boot] MPC83xx and uec
by Joakim Tjernlund 22 Oct '09

22 Oct '09

I can't find a way to get at uec_info_t/STD_UEC_INFO from my board_eth_init() in current u-boot. Am I missing something? Also drivers/qe/uec.h:int uec_initialize(bd_t *bis, uec_info_t *uec_info); include/netdev.h:int uec_initialize(int index); different prototypes for the same function.
