XAM6442ASFGGAALV: How does one initially program an attached eMMC drive on the AM6442.

Other Parts Discussed in Thread: AM6442

I have a board I designed with an XAM6442ASFGGAALV processor on it which is connected to an eMMC drive on MMC0.

I have the BOOTTMODE pins configured to boot from the eMMC drive as the primary boot source. When we put the eMMC drive chips on the board they are blank. What is the usual method for loading an initial image to the drive on the AM6442.

Is there any way to load an image into the eMMC memory using JTAG + Code Composer, the on-chip boot-rom, or any other Texas Instruments provided tools? Or do we need to write some custom code ourselves and load it into RAM via JTAG or Ethernet (our backup boot source is Ethernet) to facilitate the transfer?

While I look into this, has there been any updates/developments to this problem on your end that we should take into consideration?

Best regards,

Hey Andrew,

Please refer to the following link for eMMC flashing on AM64x EVM

Is there anything else we can assist with?

Best regards,

Andrew

So based on the link you provided we can use U-Boot to partition and load images into the eMMC drive.

The only remaining question is "can we get U-Boot into RAM via JTAG?."

I wouldn't expect loading U-Boot to be different than loading any other image into RAM, so I am assuming the answer is probably yes.

Thank you very much.
