MSP430F5659: HOW to Invoke BSL for unprogrammed chip

ganesh kumar20

Part Number: MSP430F5659

Hi All,

In my project we are using MSP430F5659 part . I want to program the fresh chip with USB BSL . How to invoke ? . I tried with power up the USB to microcontroller . In your document (SLAA452C) mentioned power up the controller with USB is enough to invoke the BSL for Blank RESET vector . Unprogrammed chip also have blank reset vector only . How to confirm whether Chip goes to BSL or not . The USB is not even detect in windows PC . I used BSL scripter application to flash the chip . Plz check below the screen shot of BSL scripter application . Please give me a solution ASAP.

Blank chip with right XT2 (4, 8 or 12 MHz) value should be enumerated on PC side as HID.
It is easier to use "MSP430 USB Firmware Upgrade Example" with GUI on Win, and not BSL scripter from CLI.

Hi Zrno Soli ,

Yes , We got proper 12 MHz clock . I tired with "MSP430 USB Firmware Upgrade Example " Software , Its not detecting USB (as HID interface) . Whether we need to install any external software plz let me know .

I will attach the snapshot of MSP430 USB Firmware Upgrade Example GUI . Its clearly shows "device not found ".

No, you don't need any extra software or driver for BSL. Device should be enumerated automatically after plugging USB cable to PC / powering up.

Okay Fine , Could you figure out this issue ! . Why its not detecting ? . Can u please send the sample circuit of USB BSL . I will check with my schematics .

HI

I checked with second method also ( Pressing RST & BSL button (VUSB connected to PUR) same time , Releasing RST after 1 second releasing BSL button .. By using this method also USB is not detected in windows ... can u suggest me how to check further .

Unfortunately, something is wrong with board / chip. Don't know if TI has board with your / or similar device. But you can use USB part of 5529 LP schematic as reference.

Hi ,
We compared the USB part of 5529 LP . I have few doubts , Please clarify it .
1) After connect the USB to PC , PUR generate 3.3V . We are not drive anything externally ? Then why we need BSL switch ? .
2) How to power up MSP430 at factory time . Any priority is there ?.
3) When we press the RST & BSL button together ? After power up the device ? or During power up .
