Posted on December 28, 2017 at 03:11Hello,
I am studying about STM32H7 using STM32H743 Nucleo-144 board with IAR.
So, I updated recently version of IAR such as ver.8.20.
When a downloading and debug, occur syntax error.
Error message is

So, I was checking this file.
Line 203 : if ((dbgmcu_cr &((0x3<<7) | (0x7<<0)) != ((0x3<<7) | (0x7<<0))) {
I think that need modify this sentence.
such as : if ((dbgmcu_cr &((0x3<<7) | (0x7<<0))) != ((0x3<<7) | (0x7<<0))) {
Please confirm me!
#dmac #iar #stm32h7
