FRDM KL-25z PK20DX128VFM5 Ic was damaged

[deepir]

In our FRDMKL-25Z board unfortunately  PK20DX128VFM5  IC was damaged, If it is possible to replace the new IC.suppose i can replace that IC,it  will work normally or not.

Otherwise  your side you feed any firmware for that IC.Please inform me.

Possible: yes.

But it might not be worthwile?

The K20 on it has a special firmware burned in with a bootloader from P&E. That firmware is not available. So if you put a new K20 on your board, you will need to re-program it with a bootloader, but it won't be the same as you have right now.

An alternative bootloader would be to use the one used on the K20 on the FRDM-K64F board.

See OpenSDAv2

But you need to keep in mind that you will need the matching firmware (P&E, Segger, CMSIS-DAP) for it.

At the end, it will be much cheaper and easier if you just buy a new FRDM-KL25Z? you still can use the KL25Z on your board I guess, simply use a P&E Multilink or a Segger, or use a second FRDM board to debug it through the SWD header.

PK20DX128VFM5 with bootloaded is available or not

[BlackNight]

It is not available with a bootloader. You will need to program it on it.

[deepir]

Yes i want to program that IC for OpenSDA

[BlackNight]

You need a SWD/JTAG programmer (like P&E Multilink or Segger J-Link) plus the firmware files from OpenSDAv2
