hi,

debugger cannot access target with external or internal supply at 1.80V

it works fine at 3V.

Same problem in JTAG mode.

Is the MSP-FET able to do targets at 1.8V ?

Hi Viggo,

Minimum supply voltage is restricted by SVS levels, please refer to Table 5-2 SVS on MSP430FR58671 datasheet for detail inforamtion. The supply voltage should be > 1.99V.

There is no way to enter SBW / JTAG mode on FR devices with 1.8 VCC. It is not related to used FET software / hardware.

I already commented this few times on e2e.

Why is TI not writing this explicitly in their datasheet for the MSP430FR58xx controllers ?
