SPNU517A.pdf, page 594 notes: 17.3 Angle Functions Engine management systems require an angle-referenced time base to synchronize signals to the engine toothed wheel. The N2HET has a method to provide such a time base for low-end engine systems. The reference is created by the N2HET using three dedicated instructions with fractional angle steps equal to /8, /16, /32, /64. Trying to wrap my head around this. They say "low-end" systems. What is "low end"? Can I spin my 32 tooth wheel to 11000 RPM and get an accurate 'angle' from this? This is going to be fun. *note- thread / topic title changed.
So in this thread I'd like to share the tinkering and research around getting OpenOCD to flash the Hercules LaunchPads. After looking into the latest stable release (0.7.0) it looks like OpenOCD has good support for its JTAG emulator--the TI XDS100v2--but it's missing a Flash library to support TI's F021 Flash API. The closest thing it has is the "tms470" driver, but that's the F05 API and after perusing the code in src/flash/nor/tms470.c, there appear to be a lot of differences. I'd like to take a crack at this one, with a stretch goal of implementing on-the-fly ECC computation so users of open-source toolchains can fully utilize the SECDED flash error detection & correction modes of the chips. Luckily, Cortex-R4 support is there although I think it was for some Atmel chip. It's a slight variation of the Cortex-A8 support, funny enough.
