Hi Everyone
I try to follow documentation of Tasking Compiler to change linking to be incremental - so far without success.

My idea to enable incremental linking through CMake + ninja was to create wrapper tools for archiver and linker. Whenever archiver is called then after static library is generated link also this library into relocatable object ( incremental linking )  

I've developed simple python wrapper script for archiver so that whenever it's called it would also run linker in incremental mode to link generated static library into relocatable object.

cctc --incremental -vv --cpu=tc39xb --force-c++ --no-exceptions --lsl-core=tc0 --lsl-file=application/linker/bootloader.lsl logger\libswc_logger.a  -o Bootloader.out

But it fails with error:

ltc F009: internal error: requested ios object property does not exist
ltc F019: unrecoverable error: fatal link error

I tried to find answer and there is nothing in the documentation what could help. Also, setting verbose output with -vv didn't add any more logs.

Non-incremental build and linking works fine.

Has anybody tried to use incremental linking feature?
Is my approach/understanding correct?
How can I debug this problem?

Thank you

Hello Champs, We have integrated the IOM driver provided as iLLD from https://github.com/Infineon/AURIX_code_examples/tree/master/code_examples/IOM_PWM_Monitor_1_KIT_TC297_TFT but we are facing some issues. We made necessary changes in the code after integration. But the IOM module is not working and we are having hard time in debugging.

Let me brief the test scenario, we would like to monitor the WDI serve (150ms) from the MCU which is routed from P_34_3. And we modified the #define DUTY_THRESHOLD 0.05 and Fspb = Fgtm = 100Mhz. we have only integrated init_Iom() into our code and smu_init() is from our MCAL. we checked the P_34_3 using oscilloscope , WDI serve is perfect. We double checked the Port configurations too. since our duty cycle is 50% and we kept the DUTY_THRESHOLD 0.05(~ 50ms) so the global event should get generated. but it isn't. We also checked in the ECU any 22k pull down resistor as mentioned https://community.infineon.com/t5/AURIX/SafeTLib-TC275-Input-Output-Monitor-IOM-Test/td-p/316063  but there is no pull down resistor.

We have observed the following: 1. IOM_LAMEWC0.CNTO shows Overflow after the initialization of IOM 2. No IOM_ECMETH0.ETA0 & IOM_ECMETH0.ETB0 is being triggered 3. No SMU ALM8.25 is being reported from SMU let me add the snippets from iLLD for reference.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

Let me add the init_Iom() from the iLLD IOM_PWM_Monitor.c, void init_Iom(void) {

/* Initialization of the port pin used in this example */ //

//Port_SetPinMode(PortConf_PortContainer_22_PORT_22_PIN_0, IfxPort_Mode_outputPushPullGeneral); /* PWM output */

Port_SetPinMode(PortConf_PortContainer_34_PORT_34_PIN_3, IfxPort_Mode_inputPullDown); /* IOM monitor input */

/* Disable interrupts */

DISABLE();

IfxIom_Driver driver;

IfxIom_Driver_Lam lam;

IfxIom_Driver_Config configDriver;

IfxIom_Driver_LamConfig configLam;

IfxIom_enableModule(); /* Initialization of the IOM module */

IfxIom_Driver_initConfig(&configDriver, &MODULE_IOM); /* Creation of default configuration */

IfxIom_Driver_init(&driver, &configDriver); /* Applying of the configuration */

IfxIom_Driver_initLamConfig(&configLam, &driver); /* Creation of a default LAM configuration */

configLam.channel = IfxIom_LamId_0; /* Selection of LAM #0 */

/* Configuration of the Monitor signal */

configLam.mon.input = IfxIom_MonInput_p34_3; /* IOM - Monitor signal input */

configLam.mon.filter.mode = IfxIom_LamFilterMode_noFilter; /* No filter applied on the signal */

configLam.mon.inverted = FALSE; /* Input signal NOT inverted */

/* Configuration of the Event Window */

configLam.eventWindow.controlSource = IfxIom_LamEventWindowControlSource_mon; /* Event window generation determined from the monitor signal */

configLam.eventWindow.run = IfxIom_LamEventWindowRunControl_freeRunning; /* Even generation window is not gated */

configLam.eventWindow.clearEvent = IfxIom_LamEventWindowClearEvent_risingEdge; /* Window cleared on the rising edge */

configLam.eventWindow.threshold = DUTY_THRESHOLD; /* Setting a threshold of 1,85ms (37% of PWM_PERIOD) */ configLam.eventWindow.inverted = TRUE; /* Window INVERTED: events are BEFORE the threshold */

/* Configuration of the IOM event */

configLam.event.source = IfxIom_LamEventSource_mon; /* Monitor signal is routed directly */

configLam.event.trigger = IfxIom_LamEventTrigger_fallingEdge; /* Falling edge used to gate event generation */ configLam.systemEventTriggerThreshold = 1; /* Alarm generated after 1 event */

IfxIom_Driver_initLam(&lam, &configLam); /* Apply the custom configuration */

lam.accumulatedCounterIndex = 1; /* Accumulated counter used */

IfxIom_Driver_enableLamEvent(&lam); /* Enable LAM events */

ENABLE();

}

from Ifxlom_cfg.h, brief LAM mon inputs , here modified to select LAM0.

typedef enum

Please help me to understand the issue. Thanks in advance.
