- DG 01:00 PM Software Development: RE: Mini SD card
- The MiniSD and MicroSD standards are both electrically identical with the same interface, only the physical size is different. So either should work just fine.
- (Posted on behalf of a customer)
We are in the process of using Micro SD card on our board. Does the Linux driver for SD card on MityArm supports Mini SD card as well?

- AS 05:03 PM PCB Development: RE: Power Management w/ MityARM
- Interesting, I thought you guys had customized it because I had interpreted from the TPS65910/AM335X User's Guide that default behavior was to stay powered off unless a startup reason was given.

- Hi Ali,
Unfortunately, the EEPROM settings in the TPS65910 are programmed in by TI prior to installation on the MityARM.
I don't think the EEPROM is programmable once it leaves TI's factory, you have to use the settings they "tuned... - AS 03:57 PM PCB Development: RE: Power Management w/ MityARM
- Hey Mike,
I've started playing with writing a "pwrbutton" driver for the TP65910 and am making some progress. We've soldered a momentary switch to PWR_ON/GND and a jumper from PMIC_INT_N to a GPIO and I can source tps65910 interrupts...

- GG 11:43 AM Software Development: RE: How to access ADC inputs from Linux kernel/application
- Hi Raja,
From what I understand there currently is no individual driver we are aware of for accessing the ADC inputs. I've been told that the touchscreen driver (drivers/input/touchscreen/ti_tsadc.c) does access the ADC. So looking i...

- Hi,
I am looking for info on how to access/configure ADC inputs from MityArm. So far i have not been able to find anything.
I need to monitor ADC pins individually. Do you have any approach on how to proceed?
Regards,
Raja.

- 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
- As always Mike your timely response is greatly appreciated.
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...

- MW 04:30 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded
- 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.
... - TI 07:47 AM Software Development: RE: Flashing NAND from SD Card
- Raja
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.
Thanks

- 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
- Hi Michael,
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).

This TI page talks about various ways to flash the NAND (from CCS, etc)
