MW 07:11 AM PCB Development: RE: MityArm 335x Minimum Voltage Operation

Hello Mr. Schantzen,
Very sorry for the delay in response.
We are looking into this spec, because at first glance I believe we may be able to lower it a bit for the module.
However, before we can alter the spec we will need to... Michael Williamson

MW 07:03 AM PCB Development: RE: VSC8601/VSC8641 PHY Discontinued

Hi Michael,
Yes, we have also seen this notification. It doesn't look like there is a drop-in replacement in the same package / footprint available, though we have only started investigating the problem.
Vitesse's product notifica... Michael Williamson

MK 02:43 PM PCB Development: VSC8601/VSC8641 PHY Discontinued

Vitesse just announced the VSC8601/VSC8641 part will be discontinued. Are there alternative PHYs that can be used? Michael Karasoff

TI 08:50 AM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND

Apologies...
I checked the git status before pushing and completely missed the board/cl tree (for some reason I was expecting to see all the files in the dir as untracked, not just the top of the untracked tree).
Anyway... I updated gi... Tim Iskander

KW 08:24 AM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND

I encountered an error building branch u-boot-2013.01. Files in board/cl/mityarm335x are missing. Here's the make error: Kim Weller

TI 03:44 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND

Finally... I have a u-boot image that will boot from the 512MB (4096k page) NAND.
It is now based on the main-line u-boot instead of the TI PSP flavor.
Use the _u-boot-2013.01_ branch from the CL repository @support.criticallink.com:/h... Tim Iskander

TI 04:15 PM Software Development: RE: Difficulty in flashing MLO and U-Boot to the AM3354 with 512MB NAND

Another pre-weekend update...
I finally (after battling mr. Murphy numerous times) got the MLO and U-Boot loading from the 4k page flash.
I need to get the rest of u-boot in order now, but the MityARM-335X DDR3 module with the 512MB fl... Tim Iskander

MW 02:33 PM Software Development: RE: RTC Not Keeping Time Between Power Cycles

BTW: If you have a smart-phone, you should be able to download a free data-matrix code reader.

Thanks for the quick reply Mike.
I modified my kernel config to enable the TPS65910.
CONFIG_RTC_DRV_TPS65910=y
#CONFIG_RTC_DRV_OMAP=y
Recompiled and tested and indeed it shows up when booting: Brian Compter

MW 01:37 PM Software Development: RE: RTC Not Keeping Time Between Power Cycles

Hi Brian,
Can you let me know which revision of AM3359 module you have? The RTC power design was updated in Rev C.
I think you either have the wrong RTC module (the AM3359 on-board RTC, which does not get power from the battery du... Michael Williamson

BC 12:42 PM Software Development: RTC Not Keeping Time Between Power Cycles

We are using a 3359 development board and have found that the RTC is not keeping time between power cycles. Each time power is cycled, the clock changes to December 23 2011 11:41 AM.
I've compiled the very latest kernel kernel (2013-... Brian Compter
