Using MSP432 with FT4232H

(1/1)

anirudh@astrome.co:
Hi,
I am using FT4232H for usb to jtag convertor for MSP432 (TI). The JTAG in MSP432 contains five pins (TCK, TMS, TDI, TDO, RST) but the datasheet of FT4232H contains the description of only 4 pins (TCK, TMS, TDI, TDO) connections. If anyone has used this before or knows about the connection of RST pin, please help.

Thanks and Regards,
Anirudh Garg

Hello,

We are not familiar with MSP432.

Refer to AN_135 FTDI MPSSE Basics as it uses the MPSSE engine to implement JTAG.

The only JTAG support can be found here:

http://www.ftdichip.com/Support/SoftwareExamples/MPSSE.htm

There are two options to use JTAG modes with the MPSSE engine:

1.            Use FTCJTAG DLL library. Example code is provided with the download (This code is no longer supported by FTDI)
2.            Use D2XX drivers direct. Example code is shown at the link above, further down the page (JTAG). AN_108 Command Processor For MPSSE and MCU Host Bus Emulation Modes provides the necessary information.

Maybe other community users have used MSP432 with JTAG and can help you further.

There is some information online which may also help you. See here as an example which is from TI's website who make the MSP432:
