AM5728: eMMC boot only on EVM

Vishal Maheshwari

Part Number: AM5728

Hi,

What is the jumper setting on AM5728 EVM to only boot from eMMC? I mean I don't want to boot from SD card in any condition (even if it is present).

Thanks!

Hi,

There is no such jumper setting. See fragment of EVM schematic below:

If not via jumper settings, can eMMC boot only be possible via some other way? Be it hardware or software!

You must change the SYSBOOT resistors on the EVM. They are located on the same page 13 of the processor module schematic (TI_AM572XEVM_REV_A3a.pdf). You can download the schematics from here: http://www.ti.com/tool/TMDSEVM572X#technicaldocuments

SYSBOOT settings are listed in section 33.2.4 of the AM572x TRM Rev. L (Table 33-9).
