Notes on w11 systems: w11a for and Nexys 3
|CPU options||FPP: no; Cache: 8 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||USB 2 speed over Cypress FX2|
The board has 8 LEDs and offers only a compactified 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 = 00101100 ti_w11 -u @<oskit-name>_boot.tcl
The Nexys 3 board was the main w11 development platforms until the Nexys 4 board arrived and development moved from ISE to Vivado. Together with the Nexys 2 board, it still has the best I/O performance thanks to the USB 2 speed and low-latency rlink connection. The sys_w11a_n3 design is occasionally FPGA tested with ostest against all oskits.
