Re: XC-1A.xn Port location names help
XMOS though could do a little more to meet the average mortal closer to half way.

Re: SP'I boot question, HW related
Yup, already got all that. The XC-1 comes without external SPI to boot from and the demos are buned into the OTP. It is configured to boot from this code in OTP. I read in the forums that there is a hack to stop it doing this and enable it to boot from external SPI. The fourm unfortunately failed to...

Re: SP'I boot question, HW related
OK got the adapter and soldered on a pin strip, So I now have a Micro SD Socket that I can plug into a socket soldered onto the XC-1, Just need to workout the connections for the SPI Boot, put an image on the card and see if it will work. It is unlikely it will, but is worth a go. Anyone know what t...

Re: SDRAM on XGC/Xshell board or LS1 device
Having and embedded language/os and development system that can fit in 8k (or at least a usable kernel) is what Forth is all about.

Re: SDRAM on XGC/Xshell board or LS1 device
Thanks for that TonyD, I was writing that piece off the cuff at silly o'clock in the morning and couldn't for the life in me remember what the designation for the latch was. Quite right you will need two for 16 bit. 29 bit (1FFFFFFF) should give you an addressable space somewhere in the region of :-...

Re: SDRAM on XGC/Xshell board or LS1 device
OK Helpful links, it's a bit old school but consider this diagram. The main parts of intrest are in the dotted box lower right hand side :- http://en.wikipedia.org/wiki/File:Intel_8085_arch.svg The 8085 is the first microcontrol system I built using wire wrap and a calculator keyboard and LED displa...

Re: Starting with Assembler
Richard Thanks for that you are also a star. I will need to alter my make file for the G4th project then to take account of this as I only want binary for Core0. Questions:- 1. what CLI tool if any would process the dumped binary into a binary plus size and crc ready to squirt down a link or write i...

Re: Starting with Assembler
Sir Awesome of Pants. I had understood a bootable (XB) to be the lump of code that you could squirt down a link and the processor would boot from it. IE it is prefixed with the size of the lump and suffixed with a CRC that validates the lump. XE on the other hand I took to be a lump of code that wou...

Re: Starting with Assembler
Yup I had picked up on that and put the relevant statements into my makefile. I like to avoid cluttering up my usual shell paths. Here's my current makefile, There is a rule vars that can be run to printout what they are all set to at the time the make file is running, so I am fairly sure it variabl...

Re: Starting with Assembler
OK That got rid of one error but leaves us with one to go. fingers@quicksilver:~/Data/Common/development/G4th$ make binary xmap G4th.o --nochaninit -save-temps --report --bootable -march=xs1b -o G4th.xb xmap: Warning: No platform specified; using default (XS1-G4B-FB512).
