davincifb driver works only at reserver memory 120M-126M using ioremap

2008-06-26 Thread steven.zhang
Hi, all. I change davincifb driver DMA buffer allocation from dma_alloc_coherent() into using ioremap() to reserver FB memory. If the reserve memory resides between 120M-126M, it works fine,while larger than 126M, its output is lines instead of linux tux. phys memory of my board is 256M, and pass

DMA Query on DM6446 CA

2008-06-26 Thread ramuni padma
Hi, I have a doubt in DMA channel configuration. Is destination address or source address increments by the element index after ACPY3_start()? If so, is the increment is same as the element index? Plz reply ASAP. Regards, Padma ___

Hi, I want to capture video from PAL cemera (4:2:2 format) by V4L2,and resize the video to 4:2:0 CIF format,there are two questions: 1,How to de-interlace two field as one frame and convert it to be CIF frame? I saw the EncodeDecode demo, which de-interlace directly with V4L2_FIELD_INTERLACED

Are you using CMEM? Typically, CMEM is configured (during 'insmod', usually from the loadmodules.sh script) to use 120MB - 128 MB. Regards, - Rob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] ] On Behalf Of steven.zhang Sent: Thursday, June 26, 2008 1:33 AM

Sorry but I'm extremely new to Linux and DaVinci but would this have anything to do with me not booting the new kernel after I built it and rebuilt the DVEVM software for the target? Tivy, Robert wrote: This sounds like you need to rebuild dm350mmap.ko against the kernel that you're booting.

Thanks Rob. But I am afraid not. You know, when FB driver is loading(on kernel booting), CMEM is not insmod(after kernel boot up) at all. Regards, Steven On Thu, 2008-06-26 at 16:41 -0500, Tivy, Robert wrote: Are you using CMEM? Typically, CMEM is configured (during 'insmod', usually from the

[PATCH RFC] ARM: Davinci: NAND fix for large page ECC and linux compatibility

2008-06-26 Thread Bernard Blackham
U-boot's HW ECC support for large page NAND on Davinci is completely broken. Some kernels, such as the 2.6.10 one supported by MontaVista for Davinci, rely upon this broken behaviour as they share the same code for ECCs. In the existing scheme, error detection *might* work on large page, but
