Flashing Mini-M4 with Jlink

[michig54]

I am new to STM and jlink and am having troubling flashing a Mikroe mini-m4 with a jlink edu mini.

I have the following pin connections:

PBA14 -> Pin 4 TCK
PBA13 -> Pin 2 TMS
PBA15 -> Pin 8 TDI
PB3 -> Pin 6 TDO
PB4 -> Pin 10 TRST
Vcc -> Pin 1
GND -> Pins 3,5,9



I created a project for STM3215RG using CubeMx, but when I try to run it using the IDE, I get the following errors:

If use JFlashLite using the hex or bin file, then I get the following errors:

I sure I am missing a set somewhere, any help would be appreciated.

Thanks!

Hi,

Can you set any programming parameters from J-Link, like COnnect under Reset and similar ?
