TMS320F2800157: MPOST Support

This device does support MPOST, however, there is a bug in some production material that results in MPOST not running at boot, even if the proper OTP locations are written to enable it.  Here is some additional information:

The OTP revision information is located at address 0x711DE.  If you see a value >1 in lower 8-bits of this address then MPOST will work as documented.  If you see 0 or 1 then above bug exists.

In this case we can give an alternate method of checking the goodness of the SRAM on the device, and that is to use the STA_MARCH test that is part of the F280015x SDL located in C2000Ware here: C:/ti/c2000/C2000Ware_5_02_00_00/libraries/diagnostic/f280015x/

This can be called as part of you main application, and will give equivalent coverage to the MPOST test.

Best,

Matthew
