The sys_w11a_c7 system is a w11a implementation for the Digilent Cmod A7-35 board.
For complete configuration, see sys_conf.vhd. The most important features are:
| Property | Value |
|---|---|
| CPU options | FPP: no; Cache: 16 kB |
| Memory | 672 kB combined from 512 kB SRAM via c7_sram_memctl and 160 kB BRAMs via pdp11_bram_memctl |
| Devices | DL11:2; DZ11, PC11, LP11, DEUNA, RK11, RL11, RHRP, TM11, IIST, KW11P, M9312: yes |
| Diagnostics | rbmon: yes; ibmon: yes; dmpcnt: yes; dmhbpt: 2; dmcmon: yes |
| Rlink | 12 Mbps via FT2232HQ based serial link |
The board has no LEDs and thus no console light emulation. The memory size of 672 kB allows starting only a subset of the available oskits. u5ed, u7ed, XXDP, RT11, RSX-11M and most most RSX-11M+ systems should work. 211bsd works only in the 'non-networking' configuration 211bsd_rpmin.
For complete instructions on how to run operating system images, see w11a_os_guide. The default setup is:
ti_w11 -tuD,12M,break,xon @<oskit-name>_boot.tcl
The Cmod A7-35 board is one of the w11 development platforms. The sys_w11a_c7 design is regularly FPGA tested with ostest against the oskits running with 672 kB memory.
