I found that when the "secure" is selected, the "Load and Go" function only can program the flash but fail to run the code then(It seems that the CPU is halted.), even by press and release the reset pin, only can run the code successfully by repowering the chip.
However, when "unsecure" is selected, the "Load and Go" function can work successfully.
Is there any solution?
The USBDM version i used is the latest version USBDM 4.10.6.
