MSP430G2533: MSP430G2533

Hello Kevin, 

Thank you for contacting us. Regarding the use of BSL communication to access memory, yes this is possible as another method even though the JTAG fuse is blown. Regarding the documentation and the know-how, I highly recommend that you reference page 331 of the MSP430G2xx User Guide linked below as well as the MSP430 Flash Devices Bootloader (BSL) User's Guide. These documentations should clarify any obscurities regarding the operation of BSL as a different access method. Kindly let me know if you have further questions thereafter!

Hi Jojo,

Thank you for your prompt response and for providing the documentation. I have reviewed the documents you attached, but I found the information to be quite high-level and generic.

I am specifically looking for detailed guidance related to the MSP430G2533 microcontroller, particularly concerning the use of the Bootstrap Loader (BSL) communication interface, to access the peripheral registers, after the JTAG fuse has been blown. Could you please provide more specific information or direct me to resources that pertain specifically to this part number?

Your assistance in providing detailed, part-specific information would be greatly appreciated.

Thank you for your continued support.

Best regards,

Kevin.

Hello Kevin, 

Thank you for that information. Nevertheless, just to be specific the MSP430G2533 follows this protocol section:  Bootloader Protocol – 1xx, 2xx, and 4xx Families. This is confirmed in the feature section on page 4: the check seen in the box of the intersection of G2xx3 and 1xx, 2xx, and 4xx protocol. 

Hi Jojo,

Thank you for your response. I appreciate the confirmation that it is possible to access the peripheral registers through the Bootstrap Loader (BSL) on the MSP430G2533 after the JTAG fuse is blown.

I am now interested in understanding whether the FlashPro 430 can be utilized for this purpose. Specifically, can FlashPro 430 be used to facilitate BSL communication to access the peripheral registers on the MSP430G2533?

If this is possible, could you please provide guidance or documentation on the setup and process involved?

Thank you for your assistance.

Best regards,
Kevin.

Hello Kevin, 

You are most welcome. Moreover, for the FlashPro 430, this is used to program only the MSP430Fxx family microcontrollers. Kindly find the user manual of the device below:

Hi Jojo,

Thank you for your response.

Currently, I am using the FlashPro 430 tool to flash the hex image onto the MSP430G2533, both through JTAG and BSL. I have a few additional questions:

1. Can the FlashPro 430 tool be used to access the peripherals (e.g., registers controlling LEDs) through BSL?
2. If yes, could you provide an example or documentation on how to access peripherals, such as controlling an LED, using the FlashPro 430 tool via BSL?
3. What is the format of the data block that I need to send through FlashPro 430 for this purpose?

Your assistance in providing detailed instructions, examples, or relevant documentation would be greatly appreciated, as it would help us better understand the capabilities of the FlashPro 430 in this context.

Thank you for your continued support.

Best regards,
Kevin.

Hello Kevin, 

Hope all is well. Nevertheless, just checking in to verify if further assistance is needed on this matter.

You are most welcome Kevin! Have a good rest of your day!
