How to build the kernel as 32-bit for ZCU102

Hi,

 

I have an pre-developed 32-bit kernel and kernel module.

Xilinx linux kernel only support 64bit configuration for ultrascale SOC (ZCU102); xilinx_zynqmp_defconfig..

 

There are the way to build the kernel as 32-bit ?

Otherwise, is there an way to execute 32-bit kernel driver on 64-bit kernel without modification (type size ...)?

Thanks quick reply. But my interesting thing is making kernel to 32-bit and cpu core works aarch32. I'm already running 32-bit application on 64-bit kernel. I hope to run 32-bit application on 32-bit kernel. But there is no corresponding defconfig.

no i think its not possible Zynq only support 64 bit Kernel. You can run 32-bit or 64-bit application
