Part Number: MSP432E401Y
Other Parts Discussed in Thread: UNIFLASH,

hi

my MSP432E401Y was assigned into a wrong set of MAC address, when i use the UniFlash to re-assign a new set of MAC address and then read it back, it's same with the previous MAC address,

obviously it doesn't work. Is it lock? Or how to re-program a new MAC address by UniFlash?

    Hello Erik,

    To erase the "User Registers" where the MAC address is stored, you can run the "Unlock Sequence" to return the device to Factory reset condition. This will erase the MAC address of the LaunchPad, the entire Flash and other non-volatile registers.

    To Unlock the device, refer the section “Executing Unlock Sequence” in the following App Note: www.ti.com/.../slaa777

    Thanks,

    Sai
