TWR-K80F150M : Bootloader OpenSDA

lacouturepatric — Sun, 25 Jun 2017 12:26:32 GMT

Hello,

I bougth a TWR-K80F150M from avnet compagny. I tried to configure the OpenSDA v2.1 bootloader but I used a Windows 10 machine . The result was I corrupted the bootloader (all led OFF on the board, no bootloader access any more). According to the doc DOC-330935, I need a Segger JLink or Keil ULink programmer attached to the JTAG port.

I need a probe to program a k80 on another board application, avnet propose us to use U-MULTILINK-FX.

Can I use a U-MULTILINK-FX to restore the bootloader or do i need Segger JLink ?

What is the diference between U-MULTILINK-FX and a Segger JLink?

Can I use the procedure from DOC-330935 to restore the bootloader with U-MULTILINK-FX?

Thank you in advance.

Regards

Hi Patrice,

you don't need any specific debug probe, any SWD/JTAG debug probe will do it (or even another Tower or FRDM board, see How to Recover the OpenSDA V2.x Bootloader | MCU on Eclipse ).

In any case, there is a setting in Windows 10 which can help preventing that problem (Bricking and Recovering OpenSDA Boards in Windows 8 and 10 | MCU on Eclipse ).

I hope this helps,

Erich
