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

- 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... - 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:

- 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...

- 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...

- BC 02:25 PM Software Development: RE: RTC Not Keeping Time Between Power Cycles
- 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: - 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... - 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-...

- According to the MityArm 335x Datasheet the minimum input voltage is 3.2VDC and the typical is 3.3VDC. Is the minimum operating voltage 3.2VDC correct? This does not leave me much margin in my 3.3V power supply design.
