208 swapped 32k and 16k ram to use block_spram. davidgb 1152d 11h /System09/trunk/rtl/
207 Updated design to pick up vdu8_spram (which uses parameterized ram for video memory instead of hard macros) davidgb 1152d 11h /System09/trunk/rtl/
206 Update comment/cleanup davidgb 1152d 12h /System09/trunk/rtl/
205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 1152d 12h /System09/trunk/rtl/
204 patched up ram for zybo use davidgb 1152d 12h /System09/trunk/rtl/
203 Added a parameterized ram model. davidgb 1152d 12h /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 1152d 13h /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 1159d 07h /System09/trunk/rtl/
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1166d 05h /System09/trunk/rtl/
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1167d 06h /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 1167d 07h /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 1174d 04h /System09/trunk/rtl/
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1174d 04h /System09/trunk/rtl/
195 Switched to using the UART over usb for the console port. davidgb 1174d 05h /System09/trunk/rtl/
194 Finally have a working board. davidgb 1174d 05h /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 1174d 09h /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 1174d 09h /System09/trunk/rtl/
189 Remove unused file. Created by ISE gui. davidgb 1181d 00h /System09/trunk/rtl/
188 update options to match what the ISE gui does davidgb 1181d 00h /System09/trunk/rtl/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1181d 05h /System09/trunk/rtl/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1181d 08h /System09/trunk/rtl/
185 Reverted back to the single-step version - something was broken davidgb 1181d 10h /System09/trunk/rtl/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1181d 11h /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 1181d 11h /System09/trunk/rtl/
178 work on constraints file davidgb 1181d 22h /System09/trunk/rtl/
177 work on zybo port davidgb 1181d 23h /System09/trunk/rtl/
176 Don't delete system09_impact.cmd on 'clean' davidgb 1182d 00h /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 1182d 00h /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 1182d 03h /System09/trunk/rtl/
173 Add another 16k BRAM for 56K total memory davidgb 1183d 23h /System09/trunk/rtl/
