Project generally working OK.
Just added Timer 6 with Interrupt using Cube and the code has been made - but the Interrupt Handler doesn't show as any generated code ( can't set breakpoint in it ).
Looking further at the Interrupt vectors...
This is the code in the file startup_stm32f030x8.s (Note no TIM6 vector)
DCD DMA1_Channel1_IRQHandler ; DMA1 Channel 1
DCD DMA1_Channel2_3_IRQHandler ; DMA1 Channel 2 and Channel 3
DCD DMA1_Channel4_5_IRQHandler ; DMA1 Channel 4 and Channel 5
DCD ADC1_IRQHandler ; ADC1
DCD TIM1_BRK_UP_TRG_COM_IRQHandler ; TIM1 Break, Update, Trigger and Commutation
DCD TIM1_CC_IRQHandler ; TIM1 Capture Compare
DCD 0 ; Reserved
DCD TIM3_IRQHandler ; TIM3
DCD 0 ; Reserved
DCD 0 ; Reserved
DCD TIM14_IRQHandler ; TIM14
DCD TIM15_IRQHandler ; TIM15
DCD TIM16_IRQHandler ; TIM16
DCD TIM17_IRQHandler ; TIM17
DCD I2C1_IRQHandler ; I2C1
DCD I2C2_IRQHandler ; I2C2
DCD SPI1_IRQHandler ; SPI1
DCD SPI2_IRQHandler ; SPI2
but this is the datasheet:

25 32 settable SPI1 SPI1 global interrupt 0x0000 00A4
26 33 settable SPI2 SPI2 global interrupt 0x0000 00A8
Note the data sheet has two positions 19 and also shows TIM6 at position 17 but with a duplicate address in 'reserved' position
I don't know if the generated code is incorrect or what is wrong - but something isn't right.
Ideas?
