My k66f frdm board doesn't wrk or get recognised on my pc anymore. I was working with it on MCU although i needed to work on a project in mbed studio therefroe i needed to update the board in order to make it work. I did the following steps and i used the following bin file to update my board.
https://www.nxp.com/downloads/en/snippets-boot-code-headers-monitors/k20dx_frdmk66f_if_crc_legacy_0x...
The above link is the firmware's download link.
I followed the following steps:
1. Hold reset button then connect the USB to PC
2. A new volume called 'BOOTLOADER' should show up.
3. Copy the latest firmware into the disk, delete the .htm file if there is not enough space available.
4. The MCU should automatically load the new firmware and reconnect itself.
5. After reconnection, if the name of the volume changed (mine changed to FRDM-K66F, could be MAINTENANCE), the update should be successful.
At step 5, My volume didn't change name and instead it stopped working. Any help and suggestion will be appreciated.
