[U-Boot-Users] A starter of porting u-boot to a new boar d
by yeshi208＠126.com 28 Apr '07

28 Apr '07

Hello: I am a newbie to use u-boot, and I have browse the readme file in the source directory. Now I want to port u-boot to a new board. But I do not know the step exactly.Could some good people tell me where should I start from:) The CPU is SEP3203F50 using ARM7TDMI core, and for the first time I want to make a u-boot.bin file to write into flash. The bin file could not surport net. Best Wishs yeshi

[U-Boot-Users] [PATCH] Use PVR to distinguish MPC5200B from MPC5200 in boot message
by Bartlomiej Sieka 27 Apr '07

27 Apr '07

MPC5200B systems are incorrectly reported as MPC5200 in U-Boot start-up message. Use PVR to distinguish between the two variants, and print proper CPU information.

[U-Boot-Users] Anyone using a Wind River SBC8560
by Mark Pilant 26 Apr '07

26 Apr '07

Hello again. I still have not made any progress trying to get u-boot to run on our Wind River eval card. (It always hangs trying to set up the CPM SCC for serial I/O.) Has anyone built a u-boot image for this (WR SBC8560) card? If so I would very much like to compare notes to find out what I am doing wrong. It is probably something simple, but so far, I have not been able to find my error. I know the card works because I have been able to build the stock Wind River boot loader/VxWorks and load/run them on the card. Thanks in advance. - Mark This email message and any attachments are confidential and may contain information which is proprietary to Mintera Corporation.

[U-Boot-Users] [PATCH] Fix memory initialization on MPC8349ITX
by Benedict, Michael 26 Apr '07

26 Apr '07

Hello, This is my first patch submission to u-boot, so let me know if the format needs to be updated. Also, I don't know how formal the sign-off procedure has to be. This patch was suggested by Bruce Leonard in his 2007/4/20 email to the list, and so I am counting that as sign-off. This patch is against the MPC83xx custodian tree, so I apologize if this should instead be sent directly to Kim Phillips. Define CFG_DDR_SDRAM_CLK_CNTL for the MPC8349ITX. This allows ddr->sdram_clk_cntl to be properly initialized, like it was before commit f6eda7f80ccc13d658020268c507d7173cf2e8aa to cpu/mpc83xx/spd_sdram.c Patch initially suggested by Timur Tabi and implemented / tested by Bruce Leonard.

[U-Boot-Users] LIBFDT: first version of fdt_find_compatible_node
by Wolfgang Grandegger 26 Apr '07

26 Apr '07

Hello, attached you can find a patch implementing fdt_find_compatible_node(): /* * Find a node based on its device type and one of the tokens in * its its "compatible" property. On success, the offset of that * node is returned or an error code: * * startoffset - the node to start searching from or 0, the node * you pass will not be searched, only the next one * will; typically, you pass 0 to start the search * and then what the previous call returned. * type - the device type string to match against * compat - the string to match to one of the tokens * in the "compatible" list. */ It should be used as shown below: offset = 0; do { offset = fdt_find_compatible_node(fdt, offset, "type", "comp"); } while (offset >= 0); This first hack also implements a cached version as alternative, because tag re-scanning might take quite long. In principle, the cache could also be used for other functions, like fdt_path_offset(), and could be invalidated in case the FDT gets updated. What do you think? Thanks. Wolfgang.
