TMDSEMU110-U: AM64xx-EVM OSPI Flash

Hi HN,

How do I erase the OSPI flash on TMDS64EVM development board using the JTAG debug cable TMDSEMU110-U in 2 scenarios below?

1. Using the CCS and attach to the JTAG cable

There's a JTAG-based flashing solution available as part of the AM64x MCU+ SDK, see here:

JTAG Uniflash

Note that as part of the process you also need to perform SOC initialization (this is highlighted in the writeup regarding JTAG Uniflash but I wanted to point it out specifically nevertheless)

SOC Initialization Using CCS Scripting

2. Linux operation

You can use the `mtd-utils` or the `dd` command to do this, see appropriate sections in the OSPI/QSPI section of the Linux SDK documentation here:
