MSP430F5529: the USB is not recognized

Can you double check if the bsl code is exist from 0x1000h to 0017FFh?

Here is the hardware connect for you to double check.

Hello Eason Zhou,

thanks for your reply.
I checked, but the code existed at 0x1000h to 0017FF.
Should I rewrite it?

Since the device can be programmed with MSP-FET, it is determined that it is not broken.

You can mass erase 5529 by FET. Connecting erased device to USB port will trigger BSL entry enumeration automatically, without PUR button.

There must be 4, 8, 12 or 24 MHz XT2 present on board.

Hello Eason Zhou,

I erased it with FET and tried it, but it doesn't seem to be recognized by PC.
I think that there is no clock problem because the board is MSP-TS430PN80USB.

Also included in MSP430USBDevelopersPackage_5_20_06_02
Using one of the examples of MSP430_USB_Software, HidDemo.jar, also included in Host_USB_Software, allows the PC and MSP-TS430PN80USB to communicate. Checking echo.

With the method using Blank RESET vector and PUR pin,
Why is USB not recognized?

Hi 

Could you measure the wave on the Q4 to see if the 4MHz crystal works well on the board?

Best regards

Hello Gary Gao,

Sorry for the late contact

The 4MHz crystal connected to XT2 of MSP-TS430PN80USB is
At the time of BSL startup, it did not seem to oscillate.
For this reason, to check if it is broken,
When XT2 was assigned to MCLK and checked,
I confirmed that it was oscillating.

Is there a problem with the BSL program?
What can be considered?

Hi DDdoor

Please capture the wave of the crystal 4MHz when BSL startup.
