thanks once again!
-
Many many thanks Mike & John, after bridging JP6 and plugging UM232H-B-NC usb in, blinking LEDs... ~:" I guessed JP6 but could not find a clear and definite identity.
-
I'm only a very little wiser.... on the LPi 1.2 boards do I need to bridge M0/JP6 or M1/JP7 for "self configure" mode? ie 1:1 seems to be both open, but which is 0:1? on the LPi 1.5.1 board "self configure" seems to be default, so should JTAG-fl…

Author xc3sprog suggests "FPGA boot mode is not right" what might this mean? I've added the verify output to my support request, but cannot see anything odd.

see xc3sprog support request for my attempt to enable Micron M25PE16 not yet working ~:"

okay, I'm a cheapskate and bought ~$15 FTDI UM232H-B-NC USB MODULE, 1 CH, 3.3V, FT232H http://uk.farnell.com/webapp/wcs/stores/servlet/ProductDisplay?partNumber=2419930 xc3sprog loads blink.bit in under a second, but when I try to load into pram/…

John, it would be great to see a write up, found this: https://github.com/daveyliam/spartan6_programmer is it that simple? thanks!

cutting the trace on LogiPi 'done' above RPi pin 22 : wfm! only a few tests such as: sudo cat /dev/urandom > /dev/fb1 and logi_loader vga_bar.bit seems to boot okay without display and run logi_loader not yet found an error message though... …
-
looking good, got stuck in, so not today... LCD does work with LPi provided pin22 is looped around, only checked with pins 19 23 25 2 22 24 so when I get a chance will check against all pins, then we can cut a trace, if we get that far.... thanks …
-
when I attach LCD to RPi only with wire connectors to pins 19 23 25 2 22 24 it works RPi alone pin 22 is +3.28v however when LogiPi only is attached pin 22 is V1 +0.9v
-
no effect this is quite hard, as display effectively covers FPGA, but I tried twice with good contact in each case.
-
further to above: if RPi 1 pin 22 is not connected to display at boot time, display does not go through setup and is not operational. LogiPi not connected.
-
Mike, V2 may be way to go, for now on V1, do hope this is not spam: Pin states tested for RPi 1: 19 23 25 2 22 24 RPi alone pin 22 is +3.28v with LogiPi V1 +0.9v other 5 pins did not appear to change.[1] tft display was not connected for these t…
-
Mike, thanks for getting back, this tft dsiplay runs okay using only pins 19 23 25 2 22 24 it has touchscreen etc, but that is minimum. the screen is detached and wire is connecting. as jpiat suggests, in theory one might use logi_loader, reboot …
-
perhaps there is a way to switch off SPI on LogiPI? and use JTAG to load hardware. it seems that something is happening on SPI as soon as power is applied? pin 18 RP_GPIO_GEN5_PROG_B is not connected for display as above pin 21 miso is also not nee…
-
Jonathan, please could you suggest alternate pins to try? or other workaround? I only connected pins 19 21 23 25 2 22 24 ie mosi miso sclk gnd 5v spio, on RPi pin 22 or GPIO25 timing? sets horizontal offset RPi displays as normal LogiPi display …
-
okay, just to be clear, in fact logi-tools is not installed, though LogiPi power up green light is on. 1M works on RPi, but not with LogiPi also tried 500k on LogiPi & 320k on RPi these did not work, ps ax 288 ? S< 0:00 [202040…

I have 2x LogiPi v1 on RPi B, (did not yet get RPi 2 working with this display.) SPI schematics pages 69-71: https://learn.adafruit.com/downloads/pdf/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi.pdf sudo nano /boot/config.txt …

NB: this case is for the Raspberry Pi 2....

am advised that Farnell UK price is being changed and should be adjusted for Monday

I'll give it a go, and comment later, thanks! ~:"

Mike, thanks again for your patience, yup I went all through the video and example, it seems well out of date and no longer applicable.** being for the Spartan3 on Papilio. But, I checked again with old version of PicoBlaze for Spartan3, I added …

quite possibly? the gadget factory link suggests: "the free Xilinx VHDL UART example is optimized for Xilinx hardware, it provides the smallest and fastest UART possible." and links to the picoblaze microcontroller. so I imagine I am looking for: …

I have chased Farnell today to ask buyer to change price on system.
