Running XMM programs from SD card

Is there any way to run an elf (or other format) xmm binary from SD card yet?

The reason I'm asking is that I'm trying to get RamBlade working with gcc XMM, but can't use propeller-load since the board needs to switch to different serial port pins between primary and secondary download.

I see there is an option to output "pex" file format, so I guess something is in the works...

    Very observant! Yes, the .pex file (Propeller Executable) is intended to be loaded from an SD card. Unfortunately, the SD loader only works on the C3 at the moment but I'm currently working on making it work on other boards. The RamBlade is on my list but I have a bit more wiring to do before my board is ready to run any software. I will address the RamBlade need for using a separate port for downloads and terminal mode.

    I'm also working on an SD cache driver that will let you run XMM code directly from the SD card. That is a bit further off.

    So, everything you are looking for is coming. Unfortunately, it's not here quite yet.

    Thanks David

    maybe you prefer to redo it yourself, anyway here's the (untested) driver.

    No, I don't prefer to do it myself. Thanks for the code! I'll try it as soon as I get my RamBlade up and running.

    Running cached XMM directly of SD will be VERY nice...
