- Gating mailbox_not empty with irq_en. bit [28] of RXCFG
- Changing elink output interrupt to "or" of not_empty and full
- Adding mailbox status register (mostly for debug)
- Moving register addresses to make space for mailbox status register
- Fixing wrappers for DV
- Updating README docs with new register map
- Removing mailbox from RX status reg. Doesn't belong there, should be coupled with mailbox for modularity.
- Turns out I had a nasty bug that was masked by using my own RX to loopback the TX. Since the new RX is very benign with a programmable fifo full flag the timing is quite relaxed.
- The legacy elink for e16 has a strict wait policy. When wait is raised high, you must stop pretty much immediately.
- I struggled with testing this bug on the parallella for 2 days.
- Putting together the test environment uncovered the bug in a couple of hours. F**K, I should know better!!
