stm32h725 injected ADC with timer 8

[ACipr.1]

Hey all,

I'm trying to trigger an ADC interrupt with timer 3 on the regular channel and timer 8 on an injected channel for both ADC 1 and 2 on the STM32H725, However, It seems like I'm only ever able to trigger the regular channel interrupt with timer 3- trying to trigger the regular channel interrupt with timer 8 also does not work and trying to trigger the injected channel interrupt doesn't work either.

Please find attached my ADC initalization file, my timer initialization file and my .ioc file. I'm trying to test this out with the standard ADC_IRQHandler!

Please let me know if there's any other information I can provide to help identify the issue here

Thanks in advance!
