- AS 02:51 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded
- Hey Mike,
That is unfortunate, I had assumed TI managed their PSP kernel like a normal upstream project. Here's hoping that they get the AM335X with device tree support in mainline stable soon. I'm not sure if you've looked at the r... - MW 12:53 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded
- Hi Ali,
We've taken the TI SDK base filesystem, tweaked the opkg configuration files to point back at the angstrom feeds and have added stuff to our filesystems. It has worked fairly well, but we haven't made a lot of different proje... - AS 12:10 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded

Thanks for the link to the meta overlay, I will definitely take a look at it. We have a couple beaglebones for prototyping and I've been successful in getting custom angstro...

- Hi Ali,
I suspect that someone copied the wiki page over from our ARM A9 products page (MityDSP-L138) which does do a native OE build using the "core" angstrom tree. Sorry about the confusion. We need to clean that page up (well, fi... - It looks like the wiki page for how the OE image for the MityARM3359 is missing:

On our L138 based SOM, we used the JFFS2 filesystem for flash based filesystem. We have not gone down the flash filesystem
path on the MityARM-3359 yet, as the dev kit boots from the SD card. There is support for both JFFS2 and UB... - RV 10:16 AM Software Development: RE: Flashing NAND from SD Card
- Hi Tim,
Thanks for your reply.
Also I am planning to flash the file system to NAND. What would be the image format to write the file system? is it UBIFS?
Do you got any procedure to create and flash the same and the image file.

Definitely a bug in the NAND layout in u-boot. I just need to test the fixes.
I wanted to get back to you before _too_ long, but I hope to be able to release a new image today.
cheers

Do we have any update on the u-boot MLO?
Appreciate your response.

- MW 12:54 PM Software Development: RE: Connecting JTAG to Mityarm board
- Raja,
A couple of thoughts come to mind:
1) If your volume is high enough, Critical Link may be able to pre-program the NAND for you.
2) You could set up a switch on your board (or use a custom "programming board" or even our De... - RV 12:16 PM Software Development: RE: Connecting JTAG to Mityarm board

Thanks for your reply.
I will try with the tera term script file.
We have just SD card available. I have tried to program and could program boot loader.
But the procedure is vast and in future if need to be program... - MW 11:01 AM Software Development: RE: Connecting JTAG to Mityarm board
- Another note:
Do you have any other I/O connections for storage such as MMC or USB Host (sticks)? If so you could load the data using those interfaces via u-Boot instead of serial (which is a little slow for large images).

Typically we load the kernel over either tftp/nfs and write it onto the MityARM-3359 flash memory or boot from nfs (http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Kernel).

I am looking in to this... I am suspecting that the u-boot MLO was not configured correctly for the nand flash partitioning scheme.

I have programmed as per the address mentioned above.

Can you get a scope on the I2C lines and set a trigger during either of the transactions above?

Your uboot image is 373252 bytes long
you are only erasing/writing 0x40000, which is 262144 (256k)
try erasing 0x80000 and use the command
U-Boot# nand write.i 0x82000000 0x40000 ${filesize}
to write it.
