Some simple RK11 drivers, especially in test codes, don't poll for completion of a write protect command. Due to the emulated I/O this can cause errors. One example is the...

minor deficit

The current w11a implementation has several deficits in the handling of traps and interrupts which lead to non-conforming behavior when multiple trap, fault and interrupt conditions occur simultaneously, for example...

bug

No `NXM` error is generated when a UNIBUS device DMA transfer reaches the top of memory in 18 bit addressing. Seen originally for RK11, but RL11 and DEUNA are also...

minor deficit

`RlinkConnect::Exec()` doesn't split command lists in case they produce a response which overflows the response buffer. Will lead to a command abort. _originally filed as issue V0.62-1 on 2014-12-20_ _issue...

incomplete

`RlinkConnect::Exec()` does not yet implement error recovery. _originally filed as issue V0.62-2 on 2014-12-20_ _issues not relevant for w11 backend over USB usage because the USB channel is usually error...

incomplete

Sounds worse than it is: all critical IOs use explicitly IOB flops, thus timing well defined. But should be resolved. _originally filed as issue V0.64-6 on 2015-03-01_

minor deficit

Some exotic RH70/RP/RM features and conditions are not yet implemented - last block transfered flag (in DS) - `CS2.BAI` currently ignored and not handled - read or write 'with header'...

incomplete

Many post-synthesis functional and especially post-routing timing simulations currently fail due to startup and initialization problems. Cause is MMCM/PLL startup, which is not properly reflected in the test bench. Will...

bug

`ti_rri` crashes in very rare cases in normal rundown (exit or ^D) when a `cuff:` type rlink is active. One gets ``` terminate called after throwing an instance of 'Retro::Rexception'...

bug

The communication to basys3 and nexys4 boards is handled via the serial port driver. The combination of the FTDI USB UART and the Linux serial port stack gives a round...
