Hi all,
I was studying juno_ADP_trm.pdf, but i don't find how to generate timer interrupt? for example, loop interrupt of 1ms.
someone did it?
We don't provide low level test software for this purpose . You will need to write this code yourself. For questions of this nature, please email juno-support@arm.com.
In short you will need to configure the GIC Distributor and GIC CPU Interfaces using the memory mapped interfaces. There are also memory mapped timers on the Juno Motherboard which can be accessed as a memory mapped device (e.g. SP804 Dual-timer @ 0x00_1C11_0000). Information about this timer can be found in the Juno TRM.
Hi Luke, thanks for your direction.
I know how to configure cpu and gic, maybe i need to know the board deeply, such as SP804.
Besides, do you think that timing-interrupt can be generated by the physical timer in A53/A57?
