Hence, I wonder if it is available for me to use mpu_wrappers.c in version 11.0.1 since I found that the wrapper is nearly the same comparing with version 10.5.1.Also, in the upgrade of rtos version, it made some freertos system call to privilege function, l...
由于硬件已经将部分寄存器压栈了,因此,xPortPendSVHandler一开始就可以使用 r0 ~ r3 寄存器。 软件压栈的这部分内容,不同的代码可能不同,比如上述代码,由于使用了 MPU,涉及到运行时特权等级的切换,需要额外记录 control 寄存器的值,于是,最终 r3 入栈了两次,一次是硬件自动压栈,另一次是上述函数中保存 control ...

-Edit os_mpu_wrappers.c so that you can write functions that disables and enables mpu and switch between user mode and priviliged mode; and use these functions before and after a critical operation. -Edit prvSetupDefaultMPU() so ...
I'm using ESP32-S3 for a project, and the FreeRTOS-MPU features would be of great use. While trying to use the "xTaskCreateRestricted", however, it appears to be undefined. Looking into the task.c file, this function is indeed not compiled due to the macro portUSING_MPU_WRAPPERS. Doe...
wolfTPM offers API wrappers to help with complex TPM operations like attestation and examples to help with complex cryptographic processes like the generation of Certificate Signing Request (CSR) using a TPM. Due to wolfTPM's portability, it is gener...
