As I have already reported that I have TMDX570LC43HDK at home. There is even Hi-Rel version of the used TMS570LC4357-EP. Gedare has some smaller boards with these chips as well. I know and have located again that there are industrial equivalents RM57L843 and RM48L740. RM are usually little endian, all TMS570 I have met are big endian.

I have not time to work or test that target, nor I have some project now and I will be quite busy next months so do not expect major contribution. But I would be happy if the development moves forward. But in the fact it would worth to start by QEMU support the first and it would take whole GSoC probably. TI AM243x seems to be interesting from this respect by possible high simmilarty to BeagleBone AM335x so probably more peripherals in QEMU could be reused... Anyway, Kamlesh Bharodiya idea to try R5 on Xilinx MPSoC which has QEMU support seems to be reasonable start direction. I have enticed that he has written somewhere notice that he has some experience with Cortex-R4. Is my understanding correct? If you have some personal or company working on some project on this target than it is even better.
