Hello. I have make a custome board with S9KEAZN64 MCU and got next trouble. I am using segger j-link edu for programming and debug. I wrote software led blink for test and start debug it. All work correcty but when i stop debug and reset power it doesn't start again. Code running from flash and i checked flash memory via segger. Binary are there. I tried to make reset pin low and high back but it doesn't help. But it is possible to start it via J-Link tool(button named start mcu or similar). What can be wrong? Thanks.
