Using custom FreeRTOS with S32K SDK and OSIF for ARM

In “Tutorial: FreeRTOS 10.0.1 with NXP S32 Design Studio 2018.R1” I showed how to use a custom FreeRTOS with the S32 Design Studio (ARM). The OSIF (OS Interface) provides an operating system and services abstraction for the application which is used by other S32K SDK components:

Converting Binary Files to Intel Hex Format with the SRecord Tool

I’m dealing a lot with bootloaders recently (see “Flash-Resident USB-HID Bootloader with the NXP Kinetis K22 Microcontroller“), and bootloaders are sometimes very picky about what file format they are able to consume. So what if I have a binary (see “S-Record, Intel Hex and Binary Files“) file and I need to convert it into the Intel Hex format?

Low Power LCD: Adafruit Breakout Board with Sharp Memory Display

Many projects benefit from a small display as a user interface. For very low power applications this is usually a no-go as the display needs too much energy. I have used e-paper displays from Kent: while these e-paper displays do not need any power to keep the image, changing the display content is not for free, plus is very slow (around 1 second needed to update the display). So I was looking for something low power and fast for a long time, until Christian (thanks!) pointed me to a display from Sharp: both very low power and fast:

Swiss Army Knife of Terminal Program for Serial Bootloaders

A bootloader shall be small and concise. I very much like bootloaders which do not need a ‘special’ program on the host, so I prefer a simple terminal for this. While porting my serial bootloader to the NXP FRDM-K64F board, I have found RealTerm which offers a lot of cool features:
