Hi,I'm stuck at a problem when using a custom bootloader.What works:All ISRs get triggered when not using the bootloaderAlmost (sic!) all ISRs get triggered when using bootloader together with my applicationWhat doesn't work:BMDA_Channel1_IRQHandler ...

Thank you both very much, indeed I've overseen the link provided as I had read the ARM documentation on that topic.It absolutely seems that was the problem. My VTOR is 0x8040200 (10th bit set) and the vector table position of BDMA_CH1 is 0x248 (10th ...

Thank you, as far as I can see, IRQs are not disabled (also see my answer below) and the system state should be handler mode (IPSR is 0x92).Is there anything else I should look at?

I'm sorry I realized that I didn't make too clear what exactly happens:When the BMDA handler should trigger, the CPU instead jumps to the defaulthandler . This happens despite all registers and memory addresses I supposed to be involved seem to be al...

Thank, you, I double checked that. VTOR is 0x8040200 so the lower 8 bits are zero, thus the alignment should be right.
