Problem from interrupts with MCU boot.
It was caused by too many interrupts declared with a non-aligned vector table. The ARM NVIC requires that the vector table must be offset to an address aligned on 4*N where N is the number of interrupts rounded to the upper power of 2. In my case I have 17 interrupts which gives 17 + 16 (standard exRead more
It was caused by too many interrupts declared with a non-aligned vector table. The ARM NVIC requires that the vector table must be offset to an address aligned on 4*N where N is the number of interrupts rounded to the upper power of 2. In my case I have 17 interrupts which gives 17 + 16 (standard exceptions) = 33 -> 64. Therefore I needed to align on 256 = 0x100. To fix the alignment I changed the header size in MCUBoot bootloader project to 0x100 instead of the default 0x80. Note that the signing command needs to be updated as well as it includes the header size in the options.

How to access the GPIO pins in RH850 series.
The hardware User Manual contains the information required to access I/O and peripherals among other things. RH850/F1KM, RH850/F1KH User's Manual: Hardware (R01UH0684EJ0110) Sample code is available to demonstrate many of the concepts.

The PWM module is not only one way to generate PWM signals. Its main purpose is to generate PWM for external devices like LEDs, where low frequencies are acceptable. PWM signals can even be generated using standard timers like TAUx. E.g. TAUDn can run up to 80 MHz (depending on the desired RH850 MCURead more
The PWM module is not only one way to generate PWM signals. Its main purpose is to generate PWM for external devices like LEDs, where low frequencies are acceptable. PWM signals can even be generated using standard timers like TAUx. E.g. TAUDn can run up to 80 MHz (depending on the desired RH850 MCU). The period and pulse width can be adjusted individually. Using an 80 MHz clock supply limit the bit width for the PWM to 10 Bit(80MHz/10Bit=78kHz).
