Hi, I have one question about Interrupts 1) Interrupts working on my board .I given one printf statement in do_irq function at that time my board is hanging othetwise Its working properly. I tested with LEDs in do_irq at that time its working properly. pls give me answer Thanks & Regards Srinivas Rao.Ch --------------------------------- Find out what India is talking about on - Yahoo!

Has anyone seen (or done) a port for the c6000 dsp family for Code Composer (TI compiler)? Thanks, Paul

I assumed you were working on the DM6446 with an ARM core and DSP and wanted to boot the board with the ARM. if that's not the case, then I am off base... __________________________________________________ Do You Yahoo!?

[U-Boot-Users] [PATCH 1/2] Add support for multiple I2C buses
by Ben Warren 07 Sep '06

07 Sep '06

Hello, Attached is a patch providing support for multiple I2C buses at the command level. The second part of the patch includes an implementation for the MPC834x CPU and MPC8349EMDS board. Note - this does not include support for 10-bit addresses. That's too profound a change to include here... Hopefully this addresses concerns with my previous attempts. Overview: 1. Include new 'i2c' command (based on USB implementation) using CONFIG_I2C_CMD_TREE. Note - I opted to not use the last remaining CMD bit in 'include/cmd_confdefs.h'. 2. Allow multiple buses by defining CONFIG_I2C_MULTI_BUS. Note that this is only available under the new 'i2c' command mentioned in bullet 1. 3. Allow by-passing of devices when probing a bus by defining CFG_I2C_MULTI_NOPROBES. This is an array of bus-device pairs that will be skipped by the 'i2c probe' command. CHANGELOG: Added new 'i2c' master command for all I2C interaction. This is conditionally compiled with CONFIG_I2C_CMD_TREE. New commands added for setting I2C bus speed as well as changing the active bus if the board has more than one bus (conditionally compiled with CONFIG_I2C_MULTI_BUS). Added a list of devices to ignore when probing the buses when more than one bus is present. Updated README. regards, Ben

[U-Boot-Users] [PATCH] Write YAFFS filesystem images to NAND
by Frank Mandarino 07 Sep '06

07 Sep '06

Hi, The attached patch for common/cmd_nand.c provides the ability to write YAFFS filesystem images to NAND flash memory, using the newer MTD-based nand code. The patch extends the nand write command to parse a ".yaffs1" suffix for yaffs1 filesystems, or a ".yaffs" or ".yaffs2" suffix for yaffs2 filesystems. Yaffs1 filesystems support 512-byte page, 16-byte oob NAND chips, while yaffs2 filesystems support 2048-byte page, 64-byte oob NAND chips. Yaffs1 filesystem images can be generated using the mkyaffsimage utility in the yaffs2/utils directory. Yaffs2 filesystem images can be generated using the mkyaffs2image utility in the yaffs2/utils directory, after applying Sergey Kubushyn's patch. See http://aleph1.co.uk/lurker/message/20060211.004601.77b55bf3.en.html. So, for example, to write a yaffs1 filesystem image of length 0x526320 from address 0x20000000 in ram to offset 0x100000 in flash, run the command: nand write.yaffs1 20000000 100000 526320 The area to be written must be erased before writing the filesystem. I have tested this code with yaffs1 filesystems, and, in fact, I am finally able to run Linux with rootfstype=yaffs. I am unable to test with yaffs2 filesystems because I don't have access to a system using 2048+64 NAND chips. Regards, ../fam -- Frank Mandarino fmandarino(a)endrelia.com Endrelia Technologies Inc.

[U-Boot-Users] ls command problem
by Srinivas rao 07 Sep '06

I have some doubts about jffs2 I loaded my jffs2 filesystem in flash 11-63 sectors. when I used ls command 1st time in u-boot in gives error like below USCP# ls Scanning JFFS2 FS: .... add_node: malloc failed add_node failed! ls: Failed to scan JFFSv2 file structure but from 2nd time onwards it giving the list of my filesystem. 1)Why 1st time it's not working ? 2) Is possible to add new file in jffs2 from u-boot?
