AM263P4: RTI Interrupt Trigger

*** Update ***

I think this is the root cause For RTI4 to RTI7 Interrupt is not  generated.

Generated code is wrong 

Actual Int num is 219

But in generated code 112 




How to by bass the code generation when building. To edit the configuration file manually and check ?

Hello Sudhakar,

I was able to verify this issue is occurring with our SysConfig data for AM263P. I'm going to talk with one of our SysConfig experts on how to resolve this, we will likely need to provide you an updated file that has the correct mapping for the interrupt.

Hello Sudhakar,

So I was hoping this would be a rather simple fix to resolve by updating some mappings, but the actual code generation here is being automated deeper in the SysConfig process and our software team will need to review and revise this.

I will inquire about what kind of patch or workaround can be provided in the meantime but for the short term until we have one available, you won't be able to access the interrupts on RTI4-7 via SysConfig.

I was looking through the generated source to see if you can just make a register write or two to resolve it but the incorrectly defined interrupt location is used as a constructing parameter for the HWI parameters so there is potential just changing the setting without changing the HWI construction would cause a system error and crash the program.

Hello Ralph,

For now, temporary workaround would be great. Kindly let me know when it is available.

Hi Sudhakar,

Will do, a few of our experts are out on holiday leave tomorrow but will review on Monday.

Hi Sudhakar,

Please find attached a patch for the issue. The same issue is applicable across Clock, Timer, RTI module and Patch fixes all of them.

Replace below files in SDK-

"source/drivers/.meta/rti/soc/rti_am263px.syscfg.js"

"source/kernel/.meta/dpl/clock_am263px.syscfg.js"

"source/kernel/.meta/dpl/timer_am263px.syscfg.js"

Do let me know if you need any further help.
