MW 02:24 PM Software Development: RE: Mityarm RGMII1 question

I think you also need to modify the devices.c.
Search for cpsw_salve_data. The phy_id needs to be assigned to the correct slave index.
The CONFIG_BASEBOARD_MITYARM335X_TESTFIXTURE actually uses the RGMII1 instead of RGMII2.

DM 02:06 PM Software Development: Mityarm RGMII1 question

I am in the process of debugging the SMSC LAN8820 PHY on a board that has a Mityarm board used as the CPU. The PHY is connected as RGMII1, with pinmux files changed in u-boot and baseboard-mityarm335x-devkit.c. I also added this new PHY ... david mckinley

Excellent glad the guide helped.
Just so you know we updated the u-boot branch with timings for the DDR to run at 400Mhz up from 303Mhz.

Successful boot of kernel 3.2 console messages. U-boot has been modified with new mii pin locations, so the kernel does not see the phy on board after booting. I can now debug the new mii phy location on my carrier board design. david mckinley

DM 12:14 PM Software Development: RE: Booting Linux

Building the Kernel with your new instruction, version: mityarm v3.2, is booting correctly. I am using gcc-linaro-arm-Linux compiler(arm-linux-gnueabi/non HW float unit) as described by the TISDK 6.0. I do have the environment-setup file... david mckinley

JC 11:15 AM Software Development: RE: Booting Linux

There shouldn't be any problem building the kernel with the SDK 06 version. Though I have not personally tested building the 3.1 branch that you are using. I'd recommend building the mityarm-linux-v3.2 as it has a lot of updates over t... Jonathan Cormier

JC 11:08 AM Software Development: RE: Booting Linux

There aren't any changes in your .config file from the one in our AM335XPSP_04.06.00.02 branch. Jonathan Cormier

JC 11:06 AM Software Development: RE: Booting Linux

Have you modified the kernel? If so were you able to boot using the unmodified version? Jonathan Cormier

DM 10:58 AM Software Development: RE: Booting Linux

I have attached the .config file. david mckinley

DM 10:42 AM Software Development: Booting Linux

I am trying to build the Kernel. After loading the Linux uImage file, I get the message:
"Uncompressing Linux... done, booting the channel" and there are no more messages.
Any Ideas?
I am using TI SDK Version 06.00.00.00
I am using... david mckinley

JC 04:20 PM Software Development: RE: Booting from Nand

Excellent this is a known issue. On boot the filesystem will try to calibrate the touch screen if its calibration file is missing. This is impossible to do if you don't actually have a touchscreen. Its looking for a @pointercal@ in th... Jonathan Cormier

BJ 03:27 PM Software Development: RE: Booting from Nand

Hello again,
Thank you for your help so far; I have been making progress, but still stuck on the NAND boot. After booting the kernel and mounting the NFS filesystem, here is where is gets stuck: Bindu Jagannatha
