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... Jonathan Cormier
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 Karasoff

02:50 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
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... Jonathan Cormier
02:31 PM Software Development: RE: Writing UBIFS rootfs to AM3354 with 512MB NAND
... Michael Karasoff
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? Jonathan Cormier
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:... Michael Karasoff

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... Michael Karasoff
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... Michael Karasoff
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... Jonathan Cormier

04:32 PM Software Development: RE: Yocto in the future?
3.2 Kernel appears to run fine under Yocto (denzil-9.0.0). Michael Karasoff
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...
Michael Williamson
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:... Michael Karasoff

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... Michael Karasoff
11:06 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
Kernel Module. Michael Karasoff
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?
Michael Williamson
06:00 PM Software Development: High Latency for GPIO Interrupts in 3.2 Kernel
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... Michael Karasoff
