08:19 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
The way the git cherry-pick command works is by taking a commit and applying it to your branch. It can be a handy to... Jonathan Cormier

05:54 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
Thanks. I'll make the change and let you know in a day or two how this works for me. Michael Karasoff
03:36 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
Okay thanks for the feedback. I'm planning on committing the following patch which should have the same effect.
P...

Yes that is it.
I've been running the kernel with this change for quite a while, and haven't seen any issues.

02:32 PM Software Development: RE: High Latency for GPIO Interrupts in 3.2 Kernel
Okay found the register in the 335x TRM:
>6.5.1.42 INTC_PENDING_IRQ3 Register (offset = F8h)

Hi Michael,
I'm trying to understand what your patch effects. Do you know what the 0xf8 register refers to? I've ...

05:18 PM Software Development: RE: How to access ADC inputs from Linux kernel/application
Not sure I see how this is a cherry pick. I don't think I've changed any history.
I appreciate that Critical Li...

03:39 PM Software Development: RE: How to access ADC inputs from Linux kernel/application
Ahh interesting. You've effectively done a manual cherry-pick. That's okay whatever gets the job done. You probabl... Jonathan Cormier
03:33 PM Software Development: RE: How to access ADC inputs from Linux kernel/application
Actually, I didn't run a "git merge". I'm forked, and my origin is my own repo. I set up a seperate remote for the ... Michael Karasoff
01:28 PM Software Development: RE: How to access ADC inputs from Linux kernel/application
I asked to clarify and to hopefully learn something. My current understanding of what you did was to merge the mitya... Jonathan Cormier
01:03 PM Software Development: RE: How to access ADC inputs from Linux kernel/application
Jonathan,
Can one not merge selected changes between two commits? Git is a powerful tool, but it hasn't redefined...

08:27 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
I'm a little confused by your merging. cl_v3.2_AM335XPSP_04.06.00.07 is a tag and not a branch and is a on the mitya... Jonathan Cormier
12:51 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
Nevermind. The problem was on my end - merge error. :)
So I have the ADC driver loaded, and I have /sys/devices/...
Michael Karasoff
12:21 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
Correction, I merged the ADC changes into cl_v3.2_AM335XPSP_04.06.00.07, not AM335XPSP_04.06.00.02.
Still the same...

12:18 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
I found the updated ADC driver code in the mityarm-linux-v3.2 branch. I merged in the ADC changes into AM335XPSP_04.... Michael Karasoff

03:19 PM Software Development: RE: Booting from Nand
Bindu,
The datasheet says the part is 4Gb which divided by 8 is 512MB. We don't have any parts that carry a nand ...

02:50 PM Software Development: RE: Booting from Nand
Jonathan, thank you for all the information. We put his task on the back burner for a while -- but it works perfectly... Bindu Jagannatha
