I am using both Nucleo-64 and Nucleo-144 boards in my project. On the Nucleo-64, the cutable PCB has been removed, and signals from CN6 on the cutoff board were tied to the Morpho connector as outlined in the docs. (NRST, SWCLK, SWDIO, and ground). The board is powered via the +5 inputs.
I get an error message indicating that the device cannot be programmed - "Cannot Load Flash Programming Algorithm".
The wiring has been double checked, so we think that's OK. Is the ground possibly screwing this up?
Any help would be appreciated.
