Re: Protect counter variable by portENTER_CRITICAL vs <atomic>
Atomics are supported, and as long as you use a 32-bit atomic, access is a lot faster as the hardware will take care of atomicity rather than needing code for critical sections.

Re: Tsens ulp instruction
You're replying to a 4-year old thread; I was talking about the 'original' ESP32 (no -S or -C suffix). I think it's indeed supported again on later chips. I guess we didn't bother to implement it in the ULP toolchain yet, though.

Re: FreeRTOS Task causes TWDT triggered
Where and how is 'var' defined? You sure it doesn't go out of scope?

Re: API to access last exception details?
You probably want to look at core dumps . Basically, you create a partition for a core dump, and whenever the ESP32 crashes, it writes relevant data there and reboots. After that, you can detect a coredump was created and do whatever with it; for instance, for systems I maintain, it uploads them via...

Re: ESP32-S3 Flash Download Tool Error: NO XMC flash detected!
They have flash, but it's not necessarily manufactured by XMC.

Re: Connect j-link to ESP32S3 chip
I cannot comment on any current activities / plans wrt cooperating with companies (mostly because I have no clue but also because I'm not sure if that's public), but we've always been forthcoming in documenting our stuff (both in the form as technical reference manuals as well as source code, e.g. t...

Re: [IoT] ESP Product Selector IoT Espressif
My colleagues are interested in RISC-V. Unfortunately, the product selector doesn't appear to let you filter for the CPU type (Xtensa or RISC-V). For most people, that is pretty uninteresting as it's abstracted away by any SDK you'd use it with. FWIW, at this point the C2, C3, C6, H2 and the future...

Re: MQTT project linker error.
I tried to build the same project with eclipse, according to your instructions, but faced the similar linker problems. Are you using another toolchain than gcc? If you post that error here, you may have a better chance of us being able to solve it. Could you please tell me the documents names ( the...
