205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 1367d 21h /System09/trunk/rtl/
204 patched up ram for zybo use davidgb 1367d 21h /System09/trunk/rtl/
203 Added a parameterized ram model. davidgb 1367d 21h /System09/trunk/rtl/
202 Updated Zybo design to reintroduce VDU8 driving the PmodVGA on pmod connectors JC+JD.
This version also uses PmodUSBUART on JE. To use PmodRS232 you must edit the .ucf file and select the appropriate pin LOCs.		 davidgb 1367d 22h /System09/trunk/rtl/
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1374d 16h /System09/trunk/rtl/
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1381d 13h /System09/trunk/rtl/
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1382d 15h /System09/trunk/rtl/
198 Update UCF file to select Pmod pinout compatible with the PmodUSBUART.
To use, make sure PmodUSBUART has JP1 as "LCL". Connect the usb to the uart and open the terminal program. Test the transmission via the LED on the Pmod. Then (carefully) plug into Pmod port on Zybo.		 davidgb 1382d 16h /System09/trunk/rtl/
197 Updates from John Kent:
-- 4.5 John Kent 2012-02-04 Re-arranged Rx & Tx Baud clock edge detect.
-- 4.6 John Kent 3021-01-30 Double sample RxC, TxC, and RxD with cpu_clk
-- for 125MHz Clock on Zybo Z7 board.		 davidgb 1389d 13h /System09/trunk/rtl/
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1389d 13h /System09/trunk/rtl/
195 Switched to using the UART over usb for the console port. davidgb 1389d 14h /System09/trunk/rtl/
194 Finally have a working board. davidgb 1389d 14h /System09/trunk/rtl/
193 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. Also fixed the 32k addressing davidgb 1389d 18h /System09/trunk/rtl/
192 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. davidgb 1389d 18h /System09/trunk/rtl/
189 Remove unused file. Created by ISE gui. davidgb 1396d 09h /System09/trunk/rtl/
188 update options to match what the ISE gui does davidgb 1396d 09h /System09/trunk/rtl/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1396d 14h /System09/trunk/rtl/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1396d 17h /System09/trunk/rtl/
185 Reverted back to the single-step version - something was broken davidgb 1396d 19h /System09/trunk/rtl/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1396d 20h /System09/trunk/rtl/
