EVM6678 - POST (external memory test)

I've not heard of this on the 6678.  We did have a similar issue on some 6670 EVMs, which we provided an update to the Intermediate Boot Loader to resolve.  It had to do with PLL initialization.

See: http://processors.wiki.ti.com/index.php/Bios_MCSDK_2.0.2_IBL_Update

Don't perform he update at the page above at this time.  I believe that there are some differences between the 6670 and 6670 EVMs that would require a different binary.  You might try the GEL file at the location above.  Initialize the PLL from the GEL and then run the POST from CCs and see if you have the same problem.

Also, I've attached the latest version of our startup GEL file for the 6678 EVM.  If this is different than yours, try this one.

Hi Dan,

I'm using the same GEL file,

Thanks,

HR,

The EVM came with Beta versions of images on EEPROM and NOR. For this test, can you update the POST image to the latest version? Follow the instructions in the User's Guide:

POST does have a version that it displays, so you can use that to make sure you have the right one. This information can be found in the MCSDK Release Notes. The latest version of POST in BIOS-MCSDK 2.0.2 is 1.0.0.3.

Also, your release is 2.0.2.14, right?

Hi Raj,

I'm running the POST program mcsdk_2_00_02_14\tools\post so I'm not using the preloaded POST program,

Thanks,

HR
