Renesas RX140 project with warnings “unused static functions”
Probably it's not the MCU and interrupts issue, but a gcc compiler issue. The compiler notices the ISR functions that are not invoked from anywhere and rises this warning. This warning happens not only in the RX-related applications. Maybe you need to select another C standard in the project propertRead more
Probably it’s not the MCU and interrupts issue, but a gcc compiler issue. The compiler notices the ISR functions that are not invoked from anywhere and rises this warning.
This warning happens not only in the RX-related applications. Maybe you need to select another C standard in the project properties (for instance switch from ISO to GNU, or try different C versions).
See lessSPI Flash Functions and Unaligned access
The spi_flash_erase_range() function should erase any size, as long as it's offset/size are a multiple of 4096 bytes and the region doesn't overflow the configured flash size. If the erase covers any 32KB aligned blocks, these are erased using the "block erase" function as this is faster than erasinRead more
The spi_flash_erase_range() function should erase any size, as long as it’s offset/size are a multiple of 4096 bytes and the region doesn’t overflow the configured flash size.
If the erase covers any 32KB aligned blocks, these are erased using the “block erase” function as this is faster than erasing 8x 4KB sectors individually.
See lessHow to assign automatically & dynamically the heap in esp32 at runtime?
There is no way to dynamically resize stack. You need to assign an amount that is large enough when you start the task.

See lessWhat is the difference Between SPI inside of SCI and Independent SPI ?
The SCI supports a so-called "Simple SPI" mode that has far less capability than the std SPI peripheral. From the hardware U/M: If your application requirements can be met by the Simple-SPI then it could be used.
