- 03:00 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- Thanks for the procedure. In case you weren't aware I wrote up a guide on doing this without the kernel being stored...
- 02:41 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- The procedure is simple - I create a UBI image (mkfs.ubifs & ubinize) with uImage and rootfile system volumes and pro...

- Michael,
I've added your changes including my alternative change to a test branch on my machine. If you could tes... - 02:48 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- Ok cool. We've never tried storing the kernel in a ubifs partition. If you have it working I'd be interested in you...

- ...
- 02:17 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- Do you have a reference for your first change? Or did you find this through trial and error?
- 02:14 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- Michael,
You should be able to replace your second change with:... - 01:41 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
- To boot from UBI with the 512MB NAND, I had to modify the 2013.01 branch bootloader:...

- 03:40 PM Software Development: RE: Yocto in the future?
- One other thing... you will need to set defconfig to the appropriate config file - it is easiest just to copy this f...
- 02:48 PM Software Development: RE: Yocto in the future?
- Sure. First I should make clear the Yocto version - it is *dylan*-9.0.0 , not denzil. This is also Yocto/Poky... la...
- 08:42 AM Software Development: RE: Yocto in the future?
- Thanks Michael for the update. Would you be willing to share the steps you did to get it working or maybe just the w...

- 04:32 PM Software Development: RE: Yocto in the future?
- 3.2 Kernel appears to run fine under Yocto (denzil-9.0.0).
- 07:35 AM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
- Thanks Michael,
We'll get it applied in the local tree (which came from TI, really).
Sorry for the inconvenie... - 03:37 AM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
- This is a bug in the kernel. Lines 215-219 of the file arch/arm/mach-omap2/irq.c should be modified:...

- 11:25 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
- The GPIO interrupt is on GPIO bank 0. Is there any chance that there is power management being applied to the GPIO o...
- 11:06 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
- Kernel Module.
- 08:12 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
- Are you handling the interrupts in a kernel module or via the gpio sysfs file hooks?
- Just switched over to the 3.2 Kernel from 3.1 to support programming of the 512MB flash, and the latency for a GPIO I...

- 03:23 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Tim,
No worries! I appreciate you getting the 512MB to work!
I downloaded from three different places on the C... - 03:15 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Mike
Sorry about that!
I did add a board type for this configuration, but didn't really document it very well. :(
... - 02:39 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Jonathan,
I found the problem - looks like a bug in your u-boot code. For some reason, the MITYARM_4K_PAGE_NAND e... - 02:21 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Jumpers only affect where the board looks for bootup code. The ubifs wiki page has my jumper config for booting from...
- 02:19 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Mike can you run "nand bad"?
Did you use an older u-boot before you got the updated one? Its possible the older u-... - 02:05 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Jonathan,
Thanks. Yes, my suspicion is that I don't have the correct u-boot. I've built u-boot from source, the ... - 09:13 AM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- Mike,
I've added the correct mtdparts and other information on flashing the nand in the following wiki: http://sup...

- 09:17 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND
- I am still having trouble programming the MLO and uboot into NAND from u-boot on an AM3354.
I've tried the MLO, uE...
