EVM430-FR6043: jtag electronic fuse

Hi,

JTAG locked FR6xx device can be mass erased (back to factory state) only by BSL. This can be done by MSP-FET and BSL Scripter.

Hi zmo,

Thank you for your quickly reply.

yes I have msp-fet device. Which pins of this device will I connect to evm430fr6043? I tried from bsl but it didn't work. Which of the bsl samples will I do? What steps do I need to follow? Is there any document?

Best regards,

Hi,

You can refer to this appnote for more information in chapter 5.3 https://www.ti.com/lit/ug/slau550aa/slau550aa.pdf

Hi Cash,

Thank you for your reply.

I have done the mentioned steps. I applied the FRxx_uart file from the ScriptExampleWindows file in BSL scripter. It gave an ACK value warning. But I saw on the forum that it means it's been deleted. Now I am trying to make the evm430fr6043 e software debugger with usb. I got a usb fet not found warning. and the led101 on the evm430fr6043 is red. I added the pictures. I am waiting for your help. thanks.

Hi,

So the Ez-FET on the EVM board is not working properly. You can open your Device Manager and check if your computer can recognize the EVM board. If not, it might be a driver issue.

Hi Cash,

Thank you for your time.

 I checked again. From evm430fr6043 it still warns that my jtag port is secured. Which pins do I need to connect when connecting msp-fet and evm430fr6043 from the jtag port. for me to mass erase.

I run bsl scripter by connecting msp-fet i vcc, test, reset, rxd, txd, gnd pins with evm430fr6043. And I get this result. I guess it didn't fix my device being in a safe state. Am I doing something wrong?

Best regards,

Hi Cash,

Thank you for your time.

Is there any update?

Hi,

For hardware invoke BSL, 5 pins are needed. TEST RST TXD RXD GND

You can try with bsl scripter or UNI-flash tool to erase the chip.

Hi Cash,

Thank you for your reply。

How is it with uniflash? Which commands should I run in bsl scripter? I've tried a lot. For example, the script I run in bsl-scripter is as follows.
I am running this script_FRxx_uart command in bsl scripter. I get this last thrown result.

Hi,

With the bsl scripter, there are two steps to erase the device. 

1. configure the UART port

2. send the wrong password 

You can open your computer's Device Manager and check which COM port is for the UART communication.

Hi Cash,

Thank you for your reply.

I am applying the uart configuration you said yes and the wrong password. But it doesn't. The result I got as a result of my experiment is in the picture.

Hi,

The process is correct. However, I missed one point before. Only the MSP-FET and MSP-BSL "Rocket" board support hardware invoke. The ez-FET on the EVM board does not support this function.

You will need get one MSP-FET and MSP-BSL "Rocket" board to do this,

Hi Cash,

Thank you for your time.

Yeah. I do these operations with msp-fet. But I always get results like this. I am using msp-fet and evm430fr6043 vcc, gnd, test, reset, rx and tx pins. I'm connecting to met-fet rx---evm rx msp-fet tx--evm tx.

Best regards,

Hi Cash,

Thank you for your support.

Is there any update?

Hi Cash,

Thank you for your support.

Hi,

Sorry for the late response. I was out of office last week. Have you tried with msp-fet tx---evm rx and msp-fet rx--evm tx?

Best regards,
