Cortex M33 non secure wifi

Hello,

I am using an NXP LPC55S69 with a Cortex M33 and Arm trustzone. The application I try to develop does some calculations in secure world and then pass the result to non-secure world where the WiFi should be located to transmit the data. For the WiFi I use the Mikroe WiFi 10 click which is placed in the Mikro bus of the board. I desparately try to init the board in the non secure world but keep getting hardfaults. Initialization in secure world works fine but I really want it to be in the non secure world but cannot figure out how to solve this. I would be really thankful for every help if anybody has some suggestiones or solved a simular issue.

Thanks and best regards,

Lukas
