I use FRDM-KL03Z and adc16_polling sample in SDK.
When I change the FOPT value from 0x3D to 0xFD for using ROM bootloader, it occur to jump default handler.
Its issue occurs only using Keil MDK-ARM. (It doesn't occur, when I use IAR EWARM.)
And it occures both P&E OpenSDA and J-Link.
<Detail of issue>
1. Change the FOPT value from 0x3D to 0xD
2. Build and debug by Keil MDK-ARM
3. Connect virtual COM and received first message from FRDM-KL03Z, and FRDM-KL03Z wait for key input
4. As soon as press a key, FRDM-KL03Z jump to default handler.
Could you tell me a reason of its issue and workaround for using MDK-ARM?
