201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1180d 22h /System09
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1187d 20h /System09
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1188d 21h /System09
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 1188d 22h /System09
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 1195d 19h /System09
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1195d 20h /System09
195 Switched to using the UART over usb for the console port. davidgb 1195d 20h /System09
194 Finally have a working board. davidgb 1195d 20h /System09
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 1196d 00h /System09
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 1196d 00h /System09
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1196d 21h /System09
190 check in file so that you do not need to generate it when running ISE in gui davidgb 1196d 21h /System09
189 Remove unused file. Created by ISE gui. davidgb 1202d 15h /System09
188 update options to match what the ISE gui does davidgb 1202d 15h /System09
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1202d 20h /System09
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1203d 00h /System09
185 Reverted back to the single-step version - something was broken davidgb 1203d 01h /System09
184 update files to correctly produce flex9ram.vhd davidgb 1203d 01h /System09
183 update file extensions davidgb 1203d 01h /System09
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1203d 01h /System09
181 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1203d 01h /System09
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1203d 02h /System09
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 1203d 02h /System09
178 work on constraints file davidgb 1203d 14h /System09
177 work on zybo port davidgb 1203d 14h /System09
176 Don't delete system09_impact.cmd on 'clean' davidgb 1203d 15h /System09
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 1203d 15h /System09
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 1203d 19h /System09
173 Add another 16k BRAM for 56K total memory davidgb 1205d 14h /System09
172 Add 16k RAM davidgb 1205d 14h /System09
