I am working with an STM32F429 in a project and I am seeing random BusFaults in random code locations, very infrequently but obviously problematic. I traced one earlier to this instruction ldr r4, [r2, #12].You'll see from the screen capture attached...

Thank you, this at least triggers an investigation around interrupt priorities.Regards, Jimi

Did anyone make any progress with this, as I have the same issue with an STM32F429. It doesn't always happen, but it periodically ends up hanging our system that never recovers.Many thanks in advance.

Thanks JW, I had totally missed this, I will set the debugger going on this and check.

So far I have checked VCAPs and voltages.I have these currently fitted https://spicat.kyocera-avx.com/product/mlcc/chartview/08053C225KAT2A.And have now ordered some of these https://www.murata.com/en-eu/products/productdetail?partno=GCM21BR71E225KA7...
