MSP430F5529: USB BSL needed for custom board to connect CCS

Thanks Leo,

This link got me to download of MSP430F55x bootloaders, no reference to the one needed to communicate to CCS, Code Composer Studio, which I think is:

Bus 003 Device 105: ID 2047:0013 Texas Instruments

tools interface.  The key is the ID 2047:0013 I think.  It came already on my EVAL board for the BLDC: DRV8350H-EVM.  We can connect to that board with CCS.  Need to connect a new board to CCS, so need that same tools driver, I guess a custom BSL-USB that connects to CCS.

Anyone know where I can get this?

Thanks,  Joe

Hi Joe,

You will need a second 5529 to act as a FET device in order to use Code Composer to program your custom board's 5529. You could use a 5529 Launchpad and just connect the Spy-by-Wire pins from the Launchpad to your custom board SBW pins. The 5529 Launchpad has eZ-FET Lite software programmed on another MSP which implements this. 

Alternatively, you can use an MSP FET to program the 5529 on your custom board:

Leo,

So you are saying we have to re-design the board to include a JTAG, as:

"The USB interface connects the MSP-FET to the computer, while the 14-pin connector provides access to the MSP debug emulation port – which consists of either a standard JTAG interface or by using the pin-saving Spy-Bi-Wire (2-wire JTAG) protocol." from the documentation.

However, I have a DRV8350H-EVM TI Brushless DC eval board that has a MSP430F5529 with only a USB connector that the CCS already talks to.  I think it is using the "Bus 003 Device 105: ID 2047:0013 Texas Instruments" interface, which my investigation indicates is a "MSP eZ-FET lite". 

This USB device shows up on my DRV8350H-EVM TI board: "Bus 003 Device 105: ID 2047:0013 Texas Instruments".

This means that an equivalent MSP eZ-FET-lite program is running on the MSP430F5529 on the DRV8350H-EVM board. 

How do I get that program to load on my new board? I can load via the BSL-Scrpter and the USB.  Once on board, then CCS will be able to connect directly.

Appreciate any help with this.

Thanks,  Joe

Hi Joe,

You don't need to redesign you're board. If you want to include an eZ-FET on your board, you need an MSP430 + the MSP430 you are trying to program on your custom board.  If you have access to the two SBW connections on your custom board, you can use a Launchpad to program your custom board via these two wires.  Let me know if this thread helps:

Leo,

The new board is already built, based upon the DRV8350H-EVM TI Brushless DC eval board.  Not feasible to add two wire JTAG.

Have downloaded the http://www.ti.com/tool/MSPDS which has the MSP-ez-lite and a lot more.

Wow, can I read out the firmware on the DRV8350H-EVM TI Brushless DC eval board.  To do so, do I need the password for that or would an incorrect password erase the entire thing?  Don't want to lose that board to development.

Have MSP430-Scripter working on new board, so could use on EVAL board to read firmware if I had the password, I think.

Does that sound feasible?  Don't want to have to re-invent this.  Just developing a new application for the BLDC board.

Thanks,   Joe

Hi Joe,
You should just be able to flash the MSP430 on your board with the ez-FET Lite image:
