Changed THUMB to ARM in startup_stm32f72bs.s, get the following message from build:
..\Stm\startup_stm32f072xb.s(153): error: A1356E: Instruction not supported on targeted CPU
2018-07-01 08:37 AM
None of the Cortex-M parts support 32-bit ARM Instructions
The Cortex-M0 supports a shrinking set of 16-bit Thumb Instructions, which means you might need to use a couple instructions to perform an operation where one instruction on a CM3 or CM4 would suffice.
