- 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...

- 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...

- 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

Sorry about that!
I did add a board type for this configuration, but didn't really document it very well. :(

- 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...

- 01:29 PM Software Development: RE: NAND memory map question
- So looking in the following file you can see that there is support in the MLO for having a redundant environment part...
- 01:08 PM Software Development: RE: NAND memory map question
- John,
Thanks for the clarification, I was looking in the kernel repository not the U-boot one.
I am not too fam... - 11:53 AM Software Development: RE: NAND memory map question
- Hi Jonathan,
Here is the wiki for the AM335x Uboot users guide:

- You can read up on the TI processor ROM boot process in section 26 of the AM335x Technical Reference Manual. http://...
- 11:10 AM Software Development: RE: NAND memory map question
- Could you please provide a reference to these TI wiki pages?
What git repo did you locate the referenced mityarm33...
