The default RDC settings are: The ARM Cortex-M4 core is assigned to RDC domain 1, and ARM Cortex-A core and other bus masters use the default assignment (RDC domain 0). For some reason people seem to fall back to "printf" debugging but that might be due to the nature (IoT?) of most projects. STMicroelectronics STM32: Cortex™-M4 Lab. I can't take credit for it - this code was provided by Joseph Yiu on a few different forums, as well as in his book (Definitive Guide to the ARM Cortex M3). NVIC is a part of the core and as such is documented in the ARM literature. However the halI2cReadData function tries to fill 64 bytes. The STM32 family of microcontrollers from STMicroelectronics is based on the ARM Cortex-M 32-bit processor core. I was studing the Clock System (CS) so i tried to source the MCLK with the very low power oscillator VLO. SDOCM00103472 If an M3/M4 core is re-started (without a reset) while in handler mode, Hwi_initStacks() fails to split the stacks SDOCM00103344 Redesign M3/M4 Hwi module to eliminate dispatch table SDOCM00103312 SYS/BIOS heap modules need better documentation for alloc() alignment requirements. NVIC in ARM Cortex-M3 (ARMv7-M) implements fixed 8-bit priority fields in Interrupt Priority Register (IPR), thereby giving us up to 256(2 8) priority levels.
