Notes on w11 systems: w11a for and Nexys 4
|CPU options||FPP: no; Cache: 32 kB|
|Memory||3840 kB from PSRAM via nx_cram_memctl_as|
|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 16 LEDs and allows a nice console light emulation. The memory size of 3840 kB allows starting all oskits.
For complete instructions on how to run operating system images, see w11a_os_guide. The default setup is:
SWI = 00000000 00101000 (gives console light display on LEDS) ti_w11 -tuD,12M,break,cts @<oskit-name>_boot.tcl
The Nexys 4 board was the main w11 development platforms until it failed in July 2019. Until July 2019 the sys_w11a_n4 design was often FPGA tested with ostest against all oskits. Since July 2019 this design is only simulation tested.
- 2019-07-20: board failed, from now on the design only simulation tested
- 2013-09-22: initial version
