C6A816x AM389x Unable to boot from SD card

James4441

I just started to work with the C6A816x EVM and have been trying to set up the board following the SDK guide. I set my system as directed:

Ubuntu 10.4 LTS

Code Sourcery

Serial connection set to 115200 8n1

Connected to the P10 UART

I ran the given setup script (${EVSDK}/setup.sh) and it looked like it was going well until it tried to use minicom to set up the board. Minicom is unable to connect at this step in the process.

I then tried to boot from an SD card. I created a SD card using the steps in the SDK Guide calling the script mksdboot.sh. That finished properly and I plugged the bard into the EVM. I started up minicom and powered on the board and was unable to see any output from the board. I tried the same thing with connecting through Hyper Term under Windows and got the same results.

Is there a step that needs to be considered that I have overlooked?

Hi,

There are a couple of things you could look at.

Is the bootmode switch settings confirgured for MMC/SD?
Are you able to boot from Nand or any other mode? If so, you could mount the card on the EVM and check if it looks ok.
Do you have a DDR3 EVM or a DDR2 EVM? The EZSDK version 5.00.00.56 supports only DDR2 EVMs.

The boot mode switches are set to - BTM[4:0] 10111

I am unable to boot from NAND mode.

As far as DDR3 vs DDR2 EVM, I am unsure about that. How would I check?

Thanks

The easiest way would be to see if you have a DDR DIMM card sticky on the top of the board.

Also, just to confirm, are you able to boot in any mode?

The EVM I have doesn't have DIMM memory, the memory is soldered to the board. After looking up the chip number of the memory it would appear that I have a DDR3 EVM.

If the 5.0.0.56 SDK won't work is there a version that does?

Hi James, The 5.00.00.56 SDK release will not work with DDR3 EVM. Is it possible to contact your local TI support, FAE or an authorized distributor? They should be able to help you further. We have a release with DDR3 support planned for end April. --Sid
