Hello :-) As the SWD seems to work it would be nice to have SWD driver for RLink implemented. Is there anyone willing to do this? Is there anyone familiar with the RLink meta language and could assist wit this task? :-)
I can see two ways of doing this driver: 1. Faster but slower ;-) It should work out of the box when we craft Transfer and Bitbang functions out of what we already know and use LibSWD for bistream generation and decomposition. This will imply slow throughput. 2. Slower but faster ;-) It would require to reverse engineer existing SWD protocol and implement driver as SWD Features that can operate on DAP with commands like AP/DP READ/WRITE. This way we can skip LibSWD and use RLink metalanguage to construct bitstream. We would the send one USB operation for DAP access and read the result. This will give way faster throughput but require more work with the driver itself. As I should present some result with Stm32Primer2 this seems to be priority task for me. However, I have more experience on FT2232 chips and would prefer to apply LibSWD on new MPSSE Interface... USB traffic dumps out of the RLink-SWD communications plus viewer/analyzer software can be found at http://files.tomek.cedro.info/electronics/arm/cortex/stm32/rlinkre/ Who is ready for the challenge? :-) Best regards :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info ------------------------------------------------------------------------------ Master Java SE, Java EE, Eclipse, Spring, Hibernate, JavaScript, jQuery and much more.
