CCS/RM42L432: How to programme RM42L432 using J-link programer instead of it's on-board programmer/debugger ?

Hello Wang,

Yes, I know that we can program using an onboard programmer but on RM42L432 Launchpad 14 pin J-TAG connector is available to program/debug MCU externally.

For this external programming without using it's on-board XDS100V2 emulator, i am trying to do with J-Link but facing issues like CCS studio hangs some time & load error.

So How to solve these errors? 

I wonder if you did step one: If this target you using has  TI's 14-pin JTAG, you need to match the standard ARM (Cortex) JTAG pin connector Segger uses.  Like, using Segger's (or similar) adapter.

Or just jump wires.

Hello,

I have manually connected jumper wires from EVK to J-link as per the images attached.

Snapshot J-link pinouts.

But yet in CCS studio not able to flash firmware using J-Link.

I am using Code Composer Studio V10 in the Ubuntu system & configured J-link Emulator in properties for debugging

In EVK 2nd pin, MCU_TRST should be connected to 3rd pin TRST Or 15th pin RESET of J-link ?

Is there dependency of Windows PC for this activity ?

Hello,

MCU_TRSTN should be connected to 3rd pin TRST of J-link.

If the JTAG cable is longer than the maximum value (10cm, please check) recommended by IEEE1149 standard, please reduce the JTAG frequency or use a buffer for JTAG signals.

Please check the JTAG clock at MCU TCK pin to make sure the clock signal is clean enough.
