Hi Alvie,

 

Thank you very much. I'm looking forward hearing from you. In the meantime I'm trying a bit...

I added to the bootloader that it shows me what data are copied from the flash and also I read them back from RAM. Data are copied correct, as war as I see.

 

My changes to boot.cpp:

extern "C" void copy_sketch(register_t spidata, unsigned crc16base, unsigned sketchsize, volatile unsigned *target){	#ifdef VERBOSE_LOADER		unsigned k=0;			#endif		while (sketchsize--) {		for (int i=4;i!=0;i--) {			spiwrite(spidata,0);			REGISTER(crc16base,ROFF_CRC16APP)=spiread(spidata);		}		#ifdef VERBOSE_LOADER		printhex(k);		printstring(": ");			k++;		#endif			unsigned tmp = spiread(spidata);		*target = tmp;		#ifdef VERBOSE_LOADER		printhex(tmp);		printstring(" - ");		tmp = *target++;		printhex(tmp);		printstring(" done\n");			#endif	}	#ifdef VERBOSE_LOADER	printstring("end: ");	printhex(k);	printstring("\n");	#endif}

The output (when loading to RAM or after applying power to the board = loaded from FLASH):

But after "Loaded, starting..." nothing happens. Maybe that helps to narrow down the problem.

Hi Alvie,

 

Just figured out I could go back in git history and check. I just run the commit 95217a1  from 30 Oct 2014. I compiles and runs fine on the papilio_one. I will now use this release and try to port it to the LX9. Thanks for your help so far. Maybe it also helps a bit to figure out, what happened since then...

Hi Alvie & Jack,

 

I got the Design running now on a Spartan 6 without using SDRAM ;) By using the code for the s3e500 from commit 95217a1  from 30 Oct 2014.

 

I vermied using a custom LX9 Board. Took a bit longer as I had to patch papilio-prog and zpuinoprogrammer to get the SPI Flash working (SST26VF064B). But the design is up and running ;)

 

I then tried to get a ngc built for using with DesignLab. I get a ngc built and when I integrate it into a schematics and build I get a lot of strange errors:

ERROR:NgdBuild:462 - input pad net 'XLXI_50_wishbone_slot_14_out_openSignal<1>'   drives multiple buffers:     pin I on block XLXI_50/Inst_ZPUino_Papilio_ProNoSD_V2_blackbox/gpio_bus_in_54_IBUF with type IBUF,     pin I on block XLXI_50/Inst_ZPUino_Papilio_ProNoSD_V2_blackbox/gpio_bus_in_53_IBUF with type IBUF,     pin I on block XLXI_50/Inst_ZPUino_Papilio_ProNoSD_V2_blackbox/gpio_bus_in_52_IBUF with type IBUF,...
ERROR:NgdBuild:924 - input pad net 'XLXI_50_wishbone_slot_14_out_openSignal<1>'   is driving non-buffer primitives:     pin G on block XST_GND with type GND,     pin I on block ext_pins_out_100_OBUFT with type OBUFT,     pin I on block ext_pins_out_99_OBUFT with type OBUFT,     pin I on block ext_pins_out_98_OBUFT with type OBUFT,     pin I on block ext_pins_out_97_OBUFT with type OBUFT,     pin I on block ext_pins_out_96_OBUFT with type OBUFT,...

The instance referred to is the one created from the schematics -> a vhf file. There I can find all the signal names that throw errors. But I cannot find the reason why. Maybe you came across the same behavior?

 

When I got things sorted out I would be glad to share the code. I just need to know where to put what, as many things are interconnected or at multiple places.

Thanks, that did it ;) Found the line (-iob xxx) in the xst file. Yes, now it's up and running! Today or latest tomorrow I should receive a different flash memory that is directly supported.

 

So for preparing uploading my changes to github I have some questions: should I create a new board id, and if, how. Alvie you mentioned before that somehow memory size is encoded there...
