I developed a board based on MKL17Z128VLH4, and it works already with my app.
Then I changed the schematic and add some new function in 2nd version, and I got new PCBA now.
But I can not load my app to MKL17Z128VLH4.
The error shows that Cannot Load Flash Programming Algorithm!.
If I change the start address of RAM for Algorithm from 0x1FFFE000 to 0x1FFFF000, I can download the app, but it runs to Hardfault_Handler error in SystemInit().
I did not change any VCC GND reset connection in 2nd version schematic.
Is any suggestions for me?
Thanks very much.
