Re: Custom trap functions

Hi, Remember to save a lower context before calling C code, restore it after the call and return from the exception with rfe. This would be a right wrapper to your user_tc_trap_protection __asm__ (".globl " "osEE_tc_trap_protection"); \ __asm__ ("osEE_tc_trap_protection" ":"); \ __asm__ ("svlcx"); \...

Re: Custom trap functions

Unfortunately, the support for custom exception handler's is not finished: the code would support it, but the generator does not support it yet. But, since all erika's files are contained in a library, you could always override a symbols providing the implementation in a file in the application. I s...

Re: linker script for running code from RAM on TriCore

What is the "global declaration of PSRAM"? Those declatations that are that are not local/self addressing This one is the self addressing one /* Program Scratch-Pad RAM (PSPR). Local Addressing */ PMI_PSRAM_local (wx!p): org = 0xC0000000, len = 32K These are the global addresses space for scratch p...

Re: malloc using

Hi, I think that using dynamic memory in a hardware AMP architecture like TriCore is looking for horrible and unnecessary troubles. In any case, it seems that the problem is that .bss segment ends aligned to 8 and the Hightec sbrk function do not allocate any guard area (as usually is done). Try to ...

Re: linker script for running code from RAM on TriCore

Start from a multicore project, and get the linker script from erika/mk folder. Copy in the root of the project and then try to customize it. Basically you should change all the the uses of flashes with the global declaration of PSRAM, moreover you have to move cost data to DSRAMs. You can use it ch...

Re: Interrupts on Erika3 and Tricore 29x with iLLD

Just to let you know, you can call RT-druid from the command line to have obtained the configuration generation (I usually work in this way). For the following I suppose that the current directory is placed where the conf.oil is located. ${RTDRUID_ECLIPSE_HOME}/evidence/generate_code.sh ${RTDRUID_EC...

Re: Interrupts on Erika3 and Tricore 29x with iLLD

Sorry I saw the ISR2 configuration in the middle of the OIL (I'm not used to search them there so I dind't see it at the beginning). I tried to generate the code from the OIL with the latest version (GH65) and I'm getting the right code: erika/obj/ee_tc_intvec.c.s ... .align 5 .globl osEE_tc_core0_i...

Re: Interrupts on Erika3 and Tricore 29x with iLLD

You are mixing 2 things, iLLD interrupt support and ERIKA support, ERIKA is not aware of iLLD is doing and iLLD is not aware to run under an ERIKA application. This means that using IFX_INTERRUPT macro to register interrupts has no use in ERIKA. In ERIKA everything is configured through OIL, you nee...

Re: How to modify Erika's demo example from TC275 to TC265DE.

Simpli change MCU_DATA from TC27X to TC26X MCU_DATA = TC26X { DERIVATIVE = "tc265de"; }; Be aware, if the demo that you are starting from has 3 core configured one has to be removed since tc265de has just 2 cores References: http://www.erika-enterprise.com/wiki/index.php?title=Infineon_Tricore_AURIX

Re: RT-Druid in HighTec Free Tool Chain IDE?

Hi, The result of the build of ERIKA is a .elf file so it can be flashed and/or debugged with any tool you have, but we provide scripts to do that only for Lauterbach TRACE32 since that is the tool we use and we do have access to. You need to contact your tool provider asking for support for the scr...

Re: TI AWR1642 build with RT-Druid : Assert on AWR1642

But, are you sure that you are working with a awr 16xx and not a 14xx (these configuration are pretty standard AFAIK), or is a custom 16xx? In any case try this: Enable compiler minimal opt: CPU_DATA = CORTEX_R { COMPILER = TI_CGT_ARM{ MINIMAL_OPTS = TRUE; }; ... }; and provide the configuration thr...

Re: Page table stage 2 translation error

So, how do you try to access this memory? It seems that you are not doing it through reference to variables, but through other techniques could you explain what are youd doing and why?
