STM32WB5x wpan examples don't seem to work #2684

Open DeppLearning opened 3 months ago

DeppLearning commented 3 months ago

I'm trying to run the stm32wb mac_ffd example on my NUCLEO-WB55RG board but get stuck here. I followed the instructions in the comments and was able to "Start Wireless Stack" eventually in Stm32 Cube Programmer. I am missing the teleprobe tool, so I used the commented line above, maybe that is an issue?

This is the log output

This is my memory.x file:

/* Change this as required for your MCU */

MEMORY
{
  /* NOTE 1 K = 1 KiBi = 1024 bytes */
  FLASH : ORIGIN = 0x08000000, LENGTH = 256K 
  RAM : ORIGIN = 0x20000000, LENGTH = 64K
}

I guess instead of LENGTH = 256K, I should use 226K but changing that didn't get me any other results.

I get similar results from running the other examples. Of the radio ones, only the tl_mbox example finishes successfully. I also tried following the flashing procedure described in the release-notes file mentioned in the comments (which is slightly different) of the embassy examples, but got the same results. Any ideas what I'm doing wrong? I am new to IEEE 802.15.4 and STM32 so I might have missed sth very obvious.

Edit: I tried an older commit (8b36a32ed5d834b23e970d5b723dd7df1f1c94a2), from around the time these examples where last updated and that seems to do the trick

DeppLearning commented 3 months ago

I tried again, the above result was probably due to some problem with the binary blobs which got fixed after trying the main branch and before trying 8b36a32ed5d834b23e970d5b723dd7df1f1c94a2. I can reproduce this, i.e. by "Delete Firmaware" in CubeProgrammer.

However, now after I got the flashing of binary blobs fixed, when I start the mac_ffd example on one board and the mac_rfd example on another, I'll get a panic on the board running mac_ffd as soon as it receives the message from the board running mac_rfd:

The same thing doesn't happen on 8b36a32ed5d834b23e970d5b723dd7df1f1c94a2 where I'll get the Hello from embassy message on the receiver and both programs keep running without panic.

I'm still seeing this on latest master. If I delete this line, the problem is gone: https://github.com/embassy-rs/embassy/blob/a2acb3e3dceddb4752f8fb1c17aa65e1959a2180/examples/stm32wb/src/bin/mac_ffd.rs#L153.

I think it's just a problem with logging the MacEvent::McpsDataInd variant. Maybe there are others, didn't try all of them but this one seems to have a problem.

I played with the wpan impl quite a bit with 3 devices and a mixture of different STM32WB55 boards (official and proprietary ones) and it seems to work well. What I noticed though is that when running with a debug probe attached (in --release) I'm seeming to lose way more packets. Same thing when I don't use a debug probe and power the device via a low-quality AC (i.e. cheapo for charging mobile phones). I guess that's somewhat expected :). Didn't see this though with other peripherals/wlan but I guess that's due to more sophisticated transport protocols there (rather than my crappy handrolled one :smile: )
