3.2.2 Software requirements
In order to change the code on the board you would need an ARM C compiler and debugger software, the
possible software options are:
- free open-source software: OpenOCD (all Olimex OpenOCD JTAG debuggers are supported in
OpenOCD)
- free software: CooCox IDE (all Olimex JTAGs are supported in CooCox)
- commercial software: EW-ARM from IAR Systems AB; CrossWorks from Rowley (all Olimex
OpenOCD JTAG debuggers are supported in IAR and Rowley Crossworks; note that our debugging tools
doesn't work in Keil MDK-ARM).
Refer to the table below for some guidance when choosing development tools.

It is a good idea to study the example that is provided by Olimex for your board. If you are not willing to
purchase the software just use the evaluation version initially.
Specifically, for STM32-P405 Olimex provides only IAR EW for ARM examples. It is a good idea to
download the latest time-limited evaluation version.
