What are the steps to reproduce this?

[PaulZC]

My guess is we've got two things trying to access the I2C bus at the same time, probably from different threads / tasks?

The u-blox GNSS instance does have a bus lock / unlock semaphore:

SparkFun_RTK_Everywhere_Firmware/Firmware/RTK_Everywhere/GNSS_ZED.ino

Line 1627 in 99b7654

bool GNSS_ZED::lock(void)

SparkFun_RTK_Everywhere_Firmware/Firmware/RTK_Everywhere/GNSS_ZED.ino

Line 2701 in 99b7654

void GNSS_ZED::unlock(void)

But it's very simple, and isolated, and only prevents the GNSS gatecrashing itself.

Do we need a combined semaphore for all the I2C bus users?

[PaulZC]

But this is on EVK... The ZED and the NEO share the same I2C bus, but the OLED has its own bus. The GNSS semaphore, simple as it is, should prevent the ZED and NEO from gatecrashing each other.

After begin and the firmware is in the loop, is there any code that attempts to discover other devices on the I2C bus?

[PaulZC]

Ah. Hang on... Each GNSS instance (ZED and NEO) currently uses their own independent iAmLocked semaphore. As a minimum, we need them to share a global gnssIsLocked semaphore.

But this is only an issue if any of the tasks running in the background attempt to access the GNSS "asynchronously". The way we have the loop structured will prevent most badness. gnss->update() and updateLBand() are called consecutively and separately.

The crash occurs during updateLBandCorrections (i2cLBand.checkUblox()) which is called by the loop - well after gnss->update(). It seems unlikely that it is the ZED and NEO fighting over the bus...

Looking at the ticker background tasks, are any of them attempting to access the GNSS or even just the I2C bus? tickerGnssLedUpdate calls gnss->isRTKFix(). On the ZED, isRTKFix() doesn't generate any bus traffic. It only returns the saved _carrierSolution. It's not that. And the EVK doesn't have a gnssStatusLED anyway. It does have pin_baseStatusLED though.

Oh. This might be it...? If the PointPerfect Library task is running, updatePplTask is called periodically. In there, if the PPL is generating corrections, zed->updateCorrectionsSource(1); can be called. And that does generate bus traffic (_zed->setVal8). It also calls gnss->pushRawData from inside the task. Yeah. That's potentially bad. If that happens while data is being read from the NEO, bad things will happen. Why would the PPL task be running on EVK? I don't know...

Or, it might be this? btReadTask can call sendGnssBuffer() to push corrections received over BT to the GNSS. That calls gnss->pushRawData. Again, if that happens while data is being read from the NEO, bad things will happen.

Maybe this can all be solved with a global gnssIsLocked semaphore? We should try...

More thoughts:

Looking to the future, with Facet Flex and the GNSS potentially sharing the I2C bus with the OLED, we almost certainly need to be more thorough about this.

EVK: the ZED and NEO share the main I2C bus; the OLED has its own auxiliary I2C bus. The main I2C bus is also accessible via the 10-way screw terminals.
Facet mosaic: the I2C bus is shared by the OLED and fuel gauge. It is also accessible via the DATA port multiplexer and the Connector board Qwiic connector.
Torch 2.1: the I2C bus is shared by the MP2762AGV charger and a USB Hub (U5).
Postcard and Shield: the main I2C bus is shared by the OLED, GPIO expander (U4 PCA9554), fuel gauge (MAX17048), the LG290P (unused). The Qwiic connector has its own auxiliary I2C bus.

Facet Flex: if the GNSS supports I2C, it will be shared with the OLED, charger (MP2762AGV), USB Hub (U5), the battery, the authentication IC, I/O expander (TCA9534).

[LeeLeahy2]

Hi Paul, The I2C driver in the core (NOT the TwoWire library) does use a semaphore to access the I2C bus.
