Flash programming & Thumb mode

Lillian XU

Hi All,

I use the Keil uVersion3 and MCBSTR9 EVAL board to run the FMI example from ST and find it is not working unless you compile the code in thumb-mode instead of ARM-mode. Can anyone give me a clue what difference between thumb and ARm mode? Why the FMI example can only work in Thumb mode? Highly appreciate any info.
