AM335x eMMC programming through JTAG

Other Parts Discussed in Thread: AM3352, AM3874

Hi,

Is there a wiki site already that shows the steps on how to use JTAG (e.g. XDS560) and CCS to program eMMC on an AM3352 CPU?

There is a site already for programming NAND flash only. I'm not quite sure if it accomodates eMMC as well.

I know that there is a wiki for programming eMMC without CCS/JTAG but since we have a XDS JTAG already and CCS I was trying to just follow what we did on our AM3874 custom boards.

Maynard,

Sorry, we at the CCS forum are not the most knowledgeable about the different flashing mechanisms of AM335x devices. There is a tool called Uniflash that supports Sitara processors, but the information on the page below does not mention eMMC:

http://processors.wiki.ti.com/index.php/Sitara_Uniflash_Quick_Start_Guide

From inside CCS, the only way I see this being possible is if an example project performs this task - I am unaware of such thing. The CCS/JTAG does not perform external flash programming of any kind, as the number of flash IC vendors and the possible combinations of interfaces (SPI, parallel, I²C, etc.) and the physical arrangement varies greatly from board to board.
