Thanks serg for the information - it all makes sense now. I was only planning to use sub_reset to see if the handle was valid when I do not have an MDIO target to test with - any of the get_* commands have the same effect on testing a valid handle, so I should never need to use sub_reset. It might b...

Hi serg, Thanks for your efforts - I did try paring it down to a simpler case but not all the way back to the original...my bad! Using your original script and slowly converging to mine, I found the issue. My code has the sub_open in a function and dev_id is global. At the start of my version of get...

Hi serg, Tried the install on a fresh machine and it does put it correctly into SysWOW64. Using SUB-20-120121-x32, the sub_app you listed returns the correct SN with both FW 0.3.3 and 0.3.5. However, with FW 0.3.5, my Python calls are still seeing the same bulk write fail, but SUBTOOL works. If you ...

Hi serg, as shown in my previous post - i get empty strings, so sub_get_serial_number() returns 0, as does sub_get_product_id() In debugging the SUB-20-120121_x32 package install, oddly, the sub20.dll goes into system32 - i thought the 64bit drivers go there and the 32bit ones go to SysWOW64 on Win7...

Is sub20.dll ver 1.26.0.0 compatible with FW=0.3.5? I FLASHed the SUB-20 with C:\Program Files\SUB-20\firmware\SUB-20_0.3.5.inc, over the 0.3.0 it shipped with. Downloaded as SUB-20-120121-x32.exe Also tried x64 version of the SUB-20 DLL with x64 Python and no difference from x32 behavior. It appear...

Hi serg,

Yes, it works with SUBTOOL. What are the compatible DLL versions with FW 0.3.5? I'm using 32-bit software package and sub20.dll in the system32 folder

Thanks,
Joel

The slow runtimes with SUB-20 might be due to slower MDC @ 1.5MHz vs 4MHz with FDI. Upgraded FW to 0.3.5 to enable CFP MSA mode and it works with SUBTOOL (32bit) @ 4MHz However, my Python code that worked with FW 0.3.0, is now broken (both sub_mdio_xfer_ex() and sub_mdio45() versions are broken now)...

The runtimes above were for 10,000 calls of read, not 100...

Hi xol and serg, Thanks for jumping in to help! 1. SUB-20-B 2. FW = 0.3.0, Lib = ? 3. Using the 34pin header for MDIO0 channel, J6 for MDIO11 4. SUBTOOL works - but READs of different addresses need to have an ADDR command before each READ. FDI's USB-MPC did not require an ADDR command preceding... ...

Turns out I had a signal integrity issue with flying leads to hookup SUB-20 to target MMD - twisting MDC with GND and MDIO with GND did the trick. Now, SUBTOOL is communicating with the target, so the SUB-20 is working good! Now just to compare my code with SUBTOOL's...
