Freescale TWR-VF65GS10 Project Specifics

Target Reset Script

The reset script in Freescale_TWR_VF65GS10_Target.js supplies the function to set up the clocks and DDR which is implemented by running the DDR initialisation project.

Flash Loaders

The loaders (click to load solution) solution has projects to build the QuadSPI0 flash loader and boot data.

Board Specific Files

The file Freescale_TWR_VF65GS10_ctl_board.c provides the SystemInit, led and button pressed function. The SystemInit function configures the DDR and for QuadSPI builds the CA5 will start the CM4 executing at it's reset address.

Known problems

The debugger cannot debug when CM4 QuadSPI0 programs have been downloaded. You will need to download using Project | Start Without Debugging, change the boot source to QuadSPI0, power cycle and use Target | Attach Debugger to debug. The debugger cannot download QuadSPI0 programs when the board has booted from QuadSPI0 so you will need to change the boot source back to SD card and power cycle.

Differential downloading into QuadSPI0 flash is not reliable. Clear the target environment option Enable Differential Download to avoid this or alternatively use the Program QuadSPI0 action on the right click context menu on the project node.
