MSP430F5529: How to enter UART BSL Mode with msp430f5529 MCU by MSP-FET?
I want to make EZ-Fet Lite and reserve USB BSL port for firmware update, but I notice that TI officially provides two hardware layouts, I don't know which one to choose.
The first layout is given by the MSP430F5529 LaunchPad Development Kit(SLAU533), and the second is given by USB Field Firmware Updates on MSP430 MCUS(SLAA452), as shown in the figures. The difference between these two connections lies in the position of the 1M Ohm pull-down resistor. Which connection should I use?
