- 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...

- 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.

Software Development: RE: u-boot question
- Thanks Tim,
That would do it.
John C. - TI 11:34 AM Software Development: RE: u-boot question
- John
That ID string is actually being printed by the MLO, not u-boot.
You'll need to reflash the MLO to see the change.
[MLO is built as part of builing u-boot]
cheers

Software Development: u-boot question
- Hi,
We have the older MITYARM 335x modules with the DDR2 and have done minor tweaking to u-boot (as in adding unzip)
but I'm having an unusual problem changing one of your printouts during u-boot:

/Tim - MK 04:58 PM Software Development: RE: Linux Can't Detect Module NAND on Custom Carrier
- We got to the bottom of this. We had some pullups on some of the higher order SYSCONFIG bits, setting boot clock to 26MHz. Took those off and it boots fine.
- MK 01:43 PM Software Development: RE: Linux Can't Detect Module NAND on Custom Carrier
- Tim,
Thanks. I've checked the pinmux settings and could find nothing that struck me as incorrect. We are using the Crticial Link's Kernel and Bootloader from the git repo. Is it possible those pinmux settings are wrong?

- Mike,
Check the pinmux settings and connections for the rest of the GPMC signals. I would think if there was an electrical issue with using your baseboard that yo would see the issue in u-boot as well.
Does your linux kernel change the... - TI 12:32 PM Software Development: RE: Pin Mux on AM3359
- Brian
On the AM335X based SOM's the linux kernel (assuming you are using linux) will need to configure all of the pin mux settings you need fro your specific application.
We don't use the pinmux tool output for anything (although it ca... - I am working with a AM3359 dev kit and need to get UART 1 and 2 working. As I understand they are configured for CAN currently.
So I expect I will have to adjust the pin mux then correct? I've seen the following pin mux utility here...

We are having a odd problem with a custom carrier, and wondering if anyone has come across a similar situation.

Software Development: RE: MityArm u-booting from SPI flash
- Mike,
I should also mention that on TI's wiki page (at the bottom) they mention that when you do build uboot for "am335x_evm_spiboot", you should
get a MLO.byteswap that is supposed to be used as the MLO. When I did the build I m...

We had to switch from the TI PSP u-boot to the mainline u-boot, which is what has kept me busy these last couple of days.
I just got to the point where I can boot the board... have not been able to check NA... -

Software Development: RE: MityArm u-booting from SPI flash
- Hey Mike,
Our SPI flash is external (on our base card on SPI bus 0), so there should not be an issue booting from it.
John C. - MW 10:18 AM Software Development: RE: MityArm u-booting from SPI flash
- Just to confirm,
You are using a MityARM-335X, right?
Are you trying to use the on-board SPI, or an external SPI?
If you are tring to use the on-board SPI, the MityARM-335x cannot boot the MLO from it. The TI AM335X ROM bootloa... -

Software Development: MityArm u-booting from SPI flash

I know we had asked about this previously but was hoping to get a little help with the flags and config file in building
u-boot/MLO for booting from SPI flash. It seemed that looking over the mityarm335x.h file if we undefin...
