Attach some flexcomm peripherals to core 1 with gcc sdk

Hi,

We are using LPC55S69-evk with the latest GCC based SDK (using CMake). We can't find out why for some peripherals, there is no suitable .cmake file for core 1 in the SDK.

As an example, there is only a "component_flexcomm_i2c_adapter_LPC55S69_cm33_core0.cmake" but no "component_flexcomm_i2c_adapter_LPC55S69_cm33_core1.cmake. However according to the MCU's datasheet, it seems possible to map i2c to core 1...

Is there any particular reason for that ?

Best regards

Hello train_hugo,

Sorry there is only SDK demo and compile for IDE version, no command version.

Hi Alice,

I believe my question wasn't clear..

I'm not searching for any sdk demo, but I'm just trying to figure out why in the GCC sdk there seems not to be full support of peripherals such as i2c or spi or any other peripheral excepting the one listed in the screenshot below.

Should I write my own .cmake files for the missing peripherals for core1 or did I miss something ?

Best regards,

Hugo

Hello train_hugo,

There isn't , you need write by yourself.

And almost project with LPC55s69 are based on IDE.

Not that it's very helpful, but ...

This is very common for free toolchains and SDKs. It is simply not possible or economic to provide support for every possible MCU/toolchain/example combination.

I have some experience with those from other providers.
