MCUXpresso IDE for KL46

[ThingPiaoChew]

I am  using MCUXpresso IDE 10.0.0 with SDK 2.2 on Freedom KL46 board . I have successfully compiled and trying to download to the board but it show no detected attached debugger .Why ?

The Freedom debugger Board information are as follows

(1P) MPN:FRDM-KL46Z

(1T) LOT:B2EB142501

(9D) DTE:1425

(2P) REV:B2

Hello,

what debug firmware have you loaded on the K20/OpenSDA of your board? CMSIS-DAP, J-Link or P&E? Note that you should use the latest and greates firmware available from OpenSDA Serial and Debug Adapter|NXP .

I hope this helps,

Erich
