can nand write.jffs2 support yaffs2 format?
dear all: I use a nand flash in dm355,the best way i can burn rootfs to flash by booting linux and mount the format yaffs2 and copy root files for avoiding bad blocks,if i am in uboot state,can i use the cmd nand write.jffs2 to burn the yaffs2 image to the address ? I have tested and it is ok,but my mtdblock3 has no bad blocks for the rootfs area,I'm not sure if it has,what will happen?it seem only support jffs2 by the name command nand write.jffs2! 2009-02-15 zuowenping ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source

NAND uboot params
What is the best way to read the bootdelay param from the linux kernel? Looks like the NAND param sector address starts from 0x4200 + 0x8, an ioremap failed. Anyone knows how to read the u-boot params on the NAND from the kernel?

Re: NAND uboot params
you can use fw_printenv and fw_setenv commands to read and set uboot environment params from the kernel. google out the commands and you will get all the neccessory info about these commands. gather bzbz wrote: What is the best way to read the bootdelay param from the linux kernel?

Building video_copy using CCS3.3
hi,all. I'm using DM6446,I want to build the video_copy using CCS3.3, the video_copy is a example of xdias6.22 but I got some errors when I builded the project. the error says can not open file 'xdc/std.h' and It's the same about other header files I'm sure I've add the directory to the compiler in customize-directories How can I fix the program?

RE: FYI: upstream-cleanup branch
This loop was added because we have observed earlier on non-linux operating system that MMC gives very fast interrupt when FIFO is 32 bytes which has caused stack overflow. In my test, count has never increased more than 1 but it may be more than 1 for some or other card. It will be better idea to write to FIFO when DXRDY/ DRRDY bit is already set instead of going out and coming back 2nd time immediately to IRQ. At first glance, it seems that it is unbounded while loop. But it has proper break if status is zero. All bits in register DAVINCI_MMCST0 are cleared by read and so read of DAVINCI_MMCST0 will certainly return zero after few iteration irrespective of any condition because controller does not report same error again. So, I feel there is no change required and we should leave it as it is. What is your view on this? It needs at least a comment, pointing out that bytes_left will either decrease to zero or there will be no more FIFO business to handle (since I/O is happening) ... so it's not unbounded even when DMA is disabled. I will add comment. Note there's another unbounded loop in the driver, which I didn't fix: the main irq handler, mmc_davinci_irq(), which is calling that handle_core_command() thing. The handle_core() thing ought to be the main body of the IRQ handler; without looping; and that spurious IRQ branch should return IRQ_NONE (and never even happen, for that matter, easily arranged). - Dave Ya, You are right mmc_davinci_irq(), which is calling that handle_core_command() in the unbounded loop. Do we really need this loop at first place? I tried after removing this unbounded loop and it seems that everything is working. What is your view on this? I agree with you that we should have IRQ_NONE. Remove that loop. I will remove this loop.

Query regarding IRAM usage on DM6467
Hi, I am Rufus Michael from ITTIAM Systems (P) Ltd. This is a query regarding the IRAM usage for audio on the DM6467 platform. These are our observations: 1. When audio capture buffers are allocated from TCM, silence is captured. 2. When audio playout buffers are allocated from TCM, silence is heard in playout. System conditions: 1. Fragment size = 1024 2. We have ensured that IRAM is enabled as mentioned in the ARM subsystem guide. 3. Physical address base for IRAM used is 0x0001. 4. Virtual address base for IRAM used is 0xe100. Can you please let us know of any erratas or in general any suggestions on the same? Thanks in advance.
