TJA1445 : interrupt configuration

sobo — Fri, 04 Sep 2026 09:44:27 GMT

Hello,

We use S32K358, with TJA1445.
we are migrating from NXP TJA1145 driver to NXP TJA1445, using EB tresos for configuration.

we don't use RXD as interrupt, but when configuring the TJA drivers in EB tresos I'm not able to deactivate it.

I set wake up support to "not supported"
I set wake up by bus, we want to be wake up by CAN pattern.
We use INH output.

but in the configuration file CanTrcv_TJA14XX_PN_Ip_Cfg.h there is this #defineCANTRCV_TJA14XX_PN_IP_USE_IPV_ICU

it forces #include "Icu.h" in the file CanTrcv_TJA14XX_PN_icu_external_access.h which depends on "Icu_Cfg.h"

but in our case we don't have the module ICU in our configuration (not needed)

How can we use the driver TJA1445 without RXD interrupt ?

Hello,

To better understand the dependency on ICU and the generated configuration, could you please provide the following information?

The RTD version currently being used and The EB Tresos version.

Thanks
