204 patched up ram for zybo use davidgb 1169d 11h /System09/trunk
203 Added a parameterized ram model. davidgb 1169d 11h /System09/trunk
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 1169d 12h /System09/trunk
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1176d 07h /System09/trunk
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1183d 04h /System09/trunk
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1184d 06h /System09/trunk
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 1184d 07h /System09/trunk
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 1191d 04h /System09/trunk
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1191d 04h /System09/trunk
195 Switched to using the UART over usb for the console port. davidgb 1191d 05h /System09/trunk
194 Finally have a working board. davidgb 1191d 05h /System09/trunk
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 1191d 09h /System09/trunk
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 1191d 09h /System09/trunk
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1192d 06h /System09/trunk
190 check in file so that you do not need to generate it when running ISE in gui davidgb 1192d 06h /System09/trunk
189 Remove unused file. Created by ISE gui. davidgb 1198d 00h /System09/trunk
188 update options to match what the ISE gui does davidgb 1198d 00h /System09/trunk
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1198d 05h /System09/trunk
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1198d 08h /System09/trunk
185 Reverted back to the single-step version - something was broken davidgb 1198d 09h /System09/trunk
