I am using E2S 5.4.0.018, KPIT GNUARM-NONE-EABI v16.01 Toolchain, RZ/T1
I need nested or multiple Interrupts on the R4F. It seems not so easy as described in the RZ/T1 Users Manual Hardware. When i set only CPSR.I to 0 in the interrupt service routine the program crashes.
What is wrong?
The interrupt service routine is declared with __attribute__((interrupt ("IRQ")));
This works fine if the interrupt is not nested, but didn’t work in my case.
Any further Hints, sample Code.
Hi chrn,The above webpage cannot be opened, is there a good solution routine or save for this problem?
Nested interrupts are awkward in armv7.
Even though I do not know exactly what you are trying to do, I would suggest to have a look at this page.
Thanks MicBis. Renesas doesn't cover Arm-specific info as one is expected to go to their documentation.
