MK 09:02 PM Software Development: RE: Yocto in the future?
Mike,
I *think* the kernel source were coming from Critical Link's git repo - this line is in the linux-mityarm-335x_3.1.bb file:
@SRC_URI = "git://support.criticallink.com/home/git/linux-mityarm-335x.git;protocol=git;branch=${BRAN...

MW 08:26 PM Software Development: RE: Yocto in the future?
Right,
If I read you correctly, you will need to modify the Yocto recipe to use our kernel URL and not Yocto's. This is because the Yocto kernel sources (or anyone else's at the moment, until we upstream stuff) does not have a MACHIN...

MK 04:45 PM Software Development: RE: Yocto in the future?
Mike,
Thanks again for your quick response.
In Yocto, I've been setting following environment variables in my local.conf:
GCCVERSION = "4.5%"
BINUVERSION = "2.20.1"
I have used pretty much the same BSP in Yocto as for Angstrom...

MW 07:28 AM Software Development: RE: Yocto in the future?
I don't know why the SDK toolchain isn't working. Are you sure that the .config file was not altered, specifically, the MACHINE type? That would definitely cause problems. Are you using the kernel and u-boot code from our site, or fro... Michael Williamson
MK 07:08 PM PCB Development: Any Experience with VSC8641 PHY?
We are building a system with extended low temperature range (below 0C) and see that the VSC8601 PHY only goes to 0C.
Vitesse also has an 8641 part with extended temperature range, which appears to be quite similar to the VSC8601, exc...

MK 05:35 PM Software Development: Yocto in the future?
Up until a week or so ago, we were developing MityARM-335x code under Angstrom as a holdover from work done on Beaglebone w/ Angstrom. We built the filesystem, kernel, and uboot using recipes posted on the Critical Link Wiki, and - once... Michael Karasoff
02:39 PM Software Development: RE: MityArm in u-booting from SPI flash
Thanks Tim,
How hard to you think it would be to merge the MityArm changes for u-boot into the latest mainline u-boot?

TI 02:28 PM Software Development: RE: MityArm in u-booting from SPI flash
John
While the omap l138 based mity SOMs do boot from SPI (NOR) flash, we have not tried to do so on the AM335X based SOMs.
In fact, the current AM335X based SOMs can not boot from on-board flash due to pin mux constraints. You should ...

02:12 PM Software Development: MityArm in u-booting from SPI flash
Does Critical Link plan to support booting from spi flash? We would like to begin the process of migrating the booting
over to spi flash and were hoping you guys might have it ready to go already (fingers crossed...) We understand that

MK 07:57 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded
I take back the comment about console-image build not working. I can build it just fine, and the issue is most certainly user error on my part.

MK 07:15 PM Software Development: RE: Critical Link Kernel integration w/ Angstrom/OpenEmbedded
After the latest angstrom update, building the console-image program no longer works, but the systemd-image works fine.
Also, I still can't figure out how to get the MLO to build. Using the one shipped with the dev kit seems to work ...

MW 08:54 AM Software Development: RE: Where is the real spi_xfer() function located for MityArm in u-boot?
Cheat:
Look for .o files.

Mike,
Thanks for the info. It is difficult to trace which files are included in the build using
the am335x_evm.h file's #defines.

John,
For the MityARM-335x family, the file is:
drivers/spi/omap3_spi.c

MW 07:50 AM Software Development: RE: Typo in rs485_test code
Hi Ian,
It depends on the version of the compiler you are using and where it is getting it's kernel headers from.
The TI tools from their 05.03.02.00 SDK, what we used to run the test, have a definition of the their serial_rs485 st...
