MSP432E401Y: How to factory reset chip

Other Parts Discussed in Thread: UNIFLASH

I have chip that gives me an error stating:

CORTEX_M4_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.1.0.00007)

I am using code composer 9.0.1.

We have tried lowering the TCLK and get the same results.

How can I factory reset the chip?

I have tried using the following command and we still get the same Error connecting after the firmware update.

xdsdfu -m

xdsdfu -f firmware.bin -r

I found several links to use ccs (scripts->default) but have no scripts availble for a factory reset.

I downloaded uniflash but am not sure how to do a factory reset using uniflash.

Hi Sean,

If you can connect device using UniFlash, maybe you can try mass erase.

Dou check the hardware or download tools's driver? I think maybe the root casue is not device.

Thanks!

When using Uniflash and trying to load the program i got the following error:

So I disconnected power and reconnected and started a new uniflash session, then I get an error stating target not connected when trying to load a program or even trying to read memory.

Hi Sean,

Have you try to use other IDE or tools to download the E401Y? Sometimes, the UniFlash is unstable and abnormal errors may occur.

Thanks!
