Description

Loaded a rainmaker example from arduino IDE on XIAO esp32c3, build successfully, crashes on XIAO. I tried 2 examples one is RMakerCustom, one is RMakerSwitch, both crashes.

Tried wifi provision and some BLE examples, all fine.

Other Steps to Reproduce

Any rainmaker example

I have checked existing issues, online documentation and the Troubleshooting Guide

• I confirm I have checked existing issues, online documentation and Troubleshooting guide.

[MingyaoLiu]

the code i pasted has some line different from the example, but loading the example and compile without modification also has the same crashing issue.
Also tried 'erase all flash before uploading', same result.

[MingyaoLiu]

I tried 2.0.6, and the examples are loading and able to do provisioning.
I saw another thread that shows there are a bunch of error in rainmaker in 2.0.7: #7893
I guess they are the same issue.

[sanketwadekar]

@SuGlider This crash is seen only when PSRAM is enabled. However, BLE memory allocation errors aren't resolved by disabling PSRAM. I've tried the WiFi Prov example and can confirm that the same errors are seen there too(errors are seen only if BT transport is used.)

[VojtechBartoska]

Thanks for your comments @sanketwadekar. Any suggestions how to fix this?

[Jason2866]

C3 has no PSRAM so this can't be the reason.
