Flashing issue in nRF52382 - using platformio


I’m facing issue in flashing the boot-loader.
I have connected my nRF52382 board with jLink & tried to burn the bootloader from the VS code-platformio

Device used: nRF52832 Bluefruit feather

Platform used : VS code - platformio

Bootloader used : .platformio/packages/framework-arduinoadafruitnrf52/bootloader/feather_nrf52832/feather_nrf52832_bootloader-0.6.2_s132_6.1.1.hex

This process does not complete, i manually need to kill the task.
Further not able to used the board.

Thankyou in advance.
