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 1186d 21h /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 1193d 18h /System09/trunk/rtl/
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1193d 18h /System09/trunk/rtl/
195 Switched to using the UART over usb for the console port. davidgb 1193d 19h /System09/trunk/rtl/
194 Finally have a working board. davidgb 1193d 19h /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 1193d 23h /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 1193d 23h /System09/trunk/rtl/
189 Remove unused file. Created by ISE gui. davidgb 1200d 14h /System09/trunk/rtl/
188 update options to match what the ISE gui does davidgb 1200d 14h /System09/trunk/rtl/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1200d 19h /System09/trunk/rtl/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1200d 22h /System09/trunk/rtl/
185 Reverted back to the single-step version - something was broken davidgb 1201d 00h /System09/trunk/rtl/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1201d 01h /System09/trunk/rtl/
179 Zybo port done to the same point as the Atlys port. The hardware appears to work but the ACIA is not communicating properly. davidgb 1201d 01h /System09/trunk/rtl/
178 work on constraints file davidgb 1201d 12h /System09/trunk/rtl/
177 work on zybo port davidgb 1201d 13h /System09/trunk/rtl/
176 Don't delete system09_impact.cmd on 'clean' davidgb 1201d 14h /System09/trunk/rtl/
175 Corrected RS-232 pin connections. Cleaned up code. Removed debug code.
System boots but the baud clock must be wrong - get garbage on hyperterm.		 davidgb 1201d 14h /System09/trunk/rtl/
174 Added button debounce. Single-step button. multiplex LED to show nibbles of addr and data for debug. Confirmed that CPU is reading from sys09swt.vhd SBug ROM correctly. Still need to debug ACIA output. davidgb 1201d 18h /System09/trunk/rtl/
173 Add another 16k BRAM for 56K total memory davidgb 1203d 13h /System09/trunk/rtl/
172 Add 16k RAM davidgb 1203d 13h /System09/trunk/rtl/
171 remove old Xess files davidgb 1203d 18h /System09/trunk/rtl/
170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.		 davidgb 1203d 18h /System09/trunk/rtl/
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 1204d 00h /System09/trunk/rtl/
168 Added more pinloc info. Switched RS-232 to use PMOD connector for more h/w debug visibility. davidgb 1204d 00h /System09/trunk/rtl/
167 Update MAP_FLAGS for z20. Update UCF to have Pmod JC for the RS-232 Pmod davidgb 1204d 13h /System09/trunk/rtl/
166 hack some pin locs. davidgb 1204d 13h /System09/trunk/rtl/
165 initial checkin for zybo z20. Still need to fix ucf file. davidgb 1204d 14h /System09/trunk/rtl/
163 more directory cleanup davidgb 1204d 14h /System09/trunk/rtl/
162 stripped down to most basic system (no vdu, keyboard, sdram, ide, etc). davidgb 1204d 14h /System09/trunk/rtl/
