 ### Gateware
-[x] rename word_dw to word_width
+[x] refactor error_cnt 
-[x] Test out CXP trigger
+[x] Heartbeat (is it useful?? lol)
-[] add __init__.py for cxp??
+[x] rename circular buffer to slots
+[x] use `from misoc.interconnect.stream import Endpoint` instead
+[x] add __init__.py for cxp??
 [] Try to fix tight s/h time pins
-[] refactor error_cnt 
+[] remove self.source.ack in fsm
-[] Heartbeat (is it useful?? lol)
+  - seems to kill timing :V
-[] rename circular buffer to slots
+[] multilane ROI
+  [] Region of interest engine (n*32 bits mode)
+  [] bus widener + fifo
 [] remove pmod/debug_sma in fns args
-[] add enum for gtx mode (e.g. tx only, rx only, both)
-   [] use if tx_mode / rx_mode instead
-[] Region of interest engine
-   [x] pixel gearbox
-   [] pixel parser (xy pos)
 [] rtio to getting the frame
   - O: trigger
   - I: frame
-[] add a packet parser module that mux the packet?
 
 ### Firmware (design with driver)
-[] Camera linkdown detection
+[x] API programming
+[x] add tag handling for api calls
+  - support lane reset in kernel using syscall
+[] double check cfg gating
+  [] add libboard_artiq/src/lib.rs cfg gating

-[] API programming
+  [] Camera linkdown detection
-[] add tag handling for api calls
+  [] add mutex support for tx/rx camera programming (or block them when camera is not ready)
-  - support line reset in kernel using syscall
+  [] add xml url printout in uart (so user can just download the xml using api)
   [] add heartbeat checking
+[] add flashing LED (non-essential)

 ### Coredevice Driver
+[x] use camera test pattern black/white to verify roi https://docs.baslerweb.com/test-patterns
+[x] test out 8/10/12 bit mode
 [] support simple camera programming interface (Not real time)
   - basic i2c-like interface with read/write u32
 [] add grabber like fns & docs
