STM32L4 nucleo board programming problem

[AVINASH PATHAK]

I have a STM32L476RG nucleo board.Recently when I tried to program it using keil I found some error messages and I was unable to program it.

I found that LD3 LED is glowing .Initially when the board was programmable it was not glowing.

I am attaching error messages of keil 5 and stlink utility.Please help to solve this problem.

Try pulling BOOT0 pin High

What is the firmware version in the ST-LINK?

Is there any way I could know what is the firmware version of stlink.I don't know what version of firmware my STlink have.

Doesn't the version show up in the transaction window of the ST-LINK Utilities, or if you click the "ST-LINK" button. There should be an Update Firmware option there which should tell you what you have and give an option to upgrade, or not.

Thank you ,keeping the Boot0 pin low worked for me.I was able to erase chip fully while keeping the boot0 pin low.Now I am able to program the board using keil.
