RE: YAFFS2 with checkpointing on DM355

Hi Chase, Thanks for the tip about disabling HW ECC. I tried doing what it says on the Wiki page (setting .eccmode = NAND_ECC_SOFT as I have LSP =1.20, the kernel config option is not there anymore). I then patched the yaffs2 with a CVS checkout of the YAFFS2 source which is 'as of' 2123 July

RE: booting a new board

Hi, You need to perform several steps 1/ Bootloader: Somebody needs to port 'u-boot' (or other bootloader) to your custom hardware. What needs changing depends on how different the hardware is from the reference platform. You will almost certainly need a JTAG probe to FLASH the bootloader.

Re: booting a new board

You have more options to do it. One is via JTAG. The othe one is via UART Reed documents SPRAAI0.pdf and SPRAAI4.pdf. There are some hints how to flash all that via UART. Good luck. Ondrej Pindroch SoftHard Technology ltd. Tel: +421(2)65459327 Fax: +421(2)65459329 Mobile:+421(904)906011

Re: Gio Interface on DM355

Hi, In arch/arm/mach-davinci/board-dm355-evm.c, have a look at the setup_ethernet() function. That will give an example as to how you can use the gpio driver. It works, thanks a lot! :D I missed the gpio_irq_type() function. :) bye! -- Andrea Gasparini ImaVis S.r.l. web:

RE: SD card performance results

Jitendra, I believe you received the location for the patches in another e-mail thread so I am just going to answer the type of SD cards I used. I used Kingston and Transcend SDHC class6 cards of size 4 and 8GB for each brand. In my testing the Transcend was faster than the Kingston.

RE: YAFFS2 with checkpointing on DM355

Phil, The issue with YAFFS was that it was not letting the MTD subsystem do the ECC. So YAFFS had an idea of where the ECC should be in the OOB area but MTD allows the ECC to be relocated by the driver. Thus YAFFS would read the wrong bits for the ECC and would think that the ECC failed because
