Hi, i have some strange in this code:
Code:
thumb

struc GPIO_RegMap
{
  .OTYPER dw ?
}

virtual at r1
  gpiob GPIO_RegMap
end virtual
ldr r0, [gpiob.CRL]
str r0, [gpiob.CRL]
    

If field CRL is missing in gpiob, compiler says "Error: (R15) not valid as second parameter" on str instruction, but if delete "thumb" - compiler says "Error: undefined symbol gpiob.CRL" on ldr instruction as it should... why str, r15, thumb?
