I am trying to program my custom board with kl25z-freedom.
Custom board has MKV31F128VLH10.
i did install USBDM and its drivers. After that i uploaded the usbdm sda firmware to kl25z.
to prevent unwanted interference i uploaded BootLoopMKL.elf file to on board mcu of kl25z.
everything was perfect. then i cut the jumper J11 on kl25z and made connections between kl25z and my sutom board.
i connected swdio, swclk and gnd and jtag_reset.
After connections are made i did power my board up and in arm programmer i clicked on detect device. flawlessly, probe detected the
MKV31F128VLH10. to make sure i did mass erase the device. erasing was successful.
But when it comes to programming flash, it fails like that in the picture
But its confusing that verify flash seems working
