Msp430f5507: Customizing Msp430 USB BSL

Part Number: MSP430F5507

Hello,

Now I'm trying to customize (modify) the Msp430 USB BSL for MSP430F5507.

I treating the project , "MSP430BSL_1_00_12_00, MSP430F552x_USB" IAR Embedded Workbench workspace.

I considered the two steps are needed , is it correct ?

1.Changing the product number from F552x to F5507 in the options

2.Adding the command options , "Compiler: --hw_workaround=CPU40
Assembler:-v1 " for avoiding errata CPU40

I wonder if any other modifying (for example, changing the source code etc.) is needed or not...

Could anyone reply to my question ?

If you are using another XT2 (not supported by TI default / factory version), it can be customized by updating binary, without messing with source code.

Hello zrno soli,

Thank you for your reply.

We would like to "output high" from specified port ( = "P5.3") at beggining of Usb Bsl(because,the oscillator IC which is connected to
XT2 port on our custom board needs to do so),
so I think we must modify the source code of Usb Bsl.

Is there any way to output high signal from specified port without modifying the source code of Usb BSL ?

Hello zrno soli,

We could custom the Usb Bsl code and could execute it. (could updating the firmware by using customized Bsl)

We had a trouble at building the Bsl code on IAR tool, but could solve it.

This community is performed by TI ,so I avoid to write the details of handling
IAR tool.

Thank you for replying.
