I do not feel competent to be main mentor for this project and some feedback from people working on RTEMS core would be helpfull. But I expect that most are on Easters now so the time to submission deadline is relatively tight. I am not sure if somebody else see potential to use RTEMS or Cortex-R5 integrated into ZCU102. I see it in general but do not see any such project on my horizon university work nor company projects horizon. I have actually neither project with TMS570LC4357, but I have at least HW and it could be nice platform to test RTEMS CAN support if it is updated during this year another GSoC and interesting platform for LwIP testing... But there is no QEMU support and I do not suggest to change your project to this direction. As I have checked, it seems that it is possible to use ZCU102 R5 somehow with local UART and timer so it makes project initial phases as feasible in the GSoC frame. Do you plan project as the longer or shorter GSoC variant? I suggest to apply before submission deadline even if the project is not fully clarified before deadline. It will be discussed by RTEMS mentors and can be slightly adjusted, extended before coding phase to match core team vision. Other option is to select another open topic which is on the RTEMS project interest list https://devel.rtems.org/wiki/Developer/OpenProjects But if you have already some experience with Cortex-R4 and see some real application use for your work then the goal has reason. You wrote in your proposal Testing R4 BSP on Qemu - but I think that there is no such available target for now As for the timeline, I suggest to move testing and familiarization with RTEMS and QEMU ecosystem into bonding period and start real coding with start of GSoC coding period to have something to to evaluate and running in the middle Testing R4 BSP on Qemu, and few other BSPs on Qemu like STM32 BSP to get familiarize myself with machines on Qemu Because if you finish work only after the second half then there is not enough time for review, clean up, documentation and adjustment for mainline submission. Expect two or three round for it and this should be real goal of GSoC and real evaluation. So I suggest move more coding to the first half and some reserve and documention and review process to the second half.
