WebOct 4, 2024 · The GIC supports trustzone. You need to put your RTOS in the secure world and Linux in the normal world. There are some settings like FIQ mode that need to be set in the secure world, so you need an smc for linux to set this. The last time I used Linux 3.xx time frame, this was in the Linux GIC drivers. – artless noise Dec 24, 2024 at 18:19 WebThe library initializes only GIC controller and debug UART memory. Memory for all other regions has to be initialized by inmate itself. At this release the ti-app is not updated. All RTOS examples don’t use the inmate library and initilizes their MMU regions by themselves. Running bare-metal ti-app.bin Here are the steps to run the demo:

WebThis is particularly important for interrutps and init of the GIC since there is only one GIC for both cores. For example, the USE_AMP flag prevents the baremetal core from initializaing the GIC because this could be be re-initializing the settings already put in place from the Linux processor.
