![]() Silicon Labs too have ARM CM4 SoCs and they give a free development environment but you need to have your own compiler toolchain installed. Atmel Studio also has a free ARM gcc toolchain, too. However, I am not aware if TI's toolchain is free. STM has given the Atollic TrueStudio for free to promote the use of their SoC's by independent developers. The easy to use toolchains are very expensive - the IAR Embedded Workbench comes in at approximately USD3000+ for a non updateable single seat license !! Keil MDK ARM is equally high on cost for individual developers. So go for a programmer from makers like Segger. So, although I haven't tried it myself, I suspect that a programmer from one of the STM would probably not support TI and Atmel SoCs, and vice versa. Most of the programmers from the SoC manufacturers have flash programming drivers that are coupled to the manufacturers' own flash devices. In my limited experience, the programming/debugging device is only half the problem :(.ĭepending on which SoC you have chosen with the M4, (STM, TI, Atmel etc), the environment to develop and compile the code is equally important. The ST Link v2 is bundled on the STM Discovery boards, which are just a couple of tens of dollars. If your requirement is only to program the M4, then the programmes are relatively inexpensive. A lot of CM4 vendors have similarly inexpensive development boards. Without a ridiculously expensive programmer.įor the MSP432, there is the "ridiculously cheap" MSP432 Launchpad, which includes a debugger/programmer interface that I think can be used to program off-board chips as well. It may or may not be useful to have an arduino program in between a PC and the built-in bootloaders. You should also consider that many CM4 chips (including the MSP432) include a built-in serial or USB bootloader, and don't NEED a separate programmer. Now, that's for debugging/programming via JTAG. The closest thing i know of is probably GitHub - ataradov/free-dap: Free and open implementation of the CMSIS-DAP debugger firmware And I don't know of anyone who has put all the pieces together and written an Arduino sketch. ![]() However, the interface for programming flash memory is NOT standardized (typically handed by a manufactuter-dependent "flash memory controller" peripheral of the chip, so it's not quite as simple as you might think.

Cortex-M4 has standardized debugging access (JTAG/SWD) and a standard USB access (CMSIS/DAP), and there is an "existence proof" in the Atmel SAMD10 Xplained Mini (which has an ATmega32u4 as it's mEDBG interface, and talks to an ARM (CM0+)) Important Information for this Arm website. Is it possible to program a Cortex M4 that way? ![]()
