My project doesn't have startup file, project is executed as a function from boot code which is runned through RAM.
We need to install ISR vector address manually using NVIC_SetVector API.
I am facing like "USIC2_3_IRQHandler' are undeclared .
Kindly help in resolving the issue.
What XMC device are you using ? Will you be able to share your code snippet to recreate the issue at our end ?
