RM46L852: Programming Guide

Hi ,

RM46Lx is ARM Cortex-R4F based microcontrollr. Here is the programmer guide from ARM website:

TI provides a code generate tool to allow users to generate hardware abstraction layer device drivers for Hercules microcontrollers. HALCoGen provides a graphical user interface that allows the user to configure peripherals, interrupts, clocks, and other Hercules microcontroller parameters. Once the Hercules device is configured, the user can generate peripheral initialization and driver code, which can be imported into CCS, IAR Workbench, etc.

Hi Peter,

Yes, the F021 flash APIs can be used to erase/program the flash. The user guide is located in the installation folder of the Flash Library:

This is the link to download the Flash API:

Does JTAG Programmer Overview for Hercules-Based Microcontrollers help?

The start of the abstract is:

This application report describes the necessary steps needed by the third party developers to create a JTAG-based flash programmer for the Hercules family of microcontrollers.
