Re: JTAG Debug Problem

What OS are you using? What hardware are you using? Does the serial port on the hardware work?

Re: CLK on SPI master ESP32

Make sure that your buscfg and devcfg are zeroed out first. At the moment, you're getting random crap from the stack in members of those structures that you didn't explicitly fill in.

Re: SD example crashs on ESP-WROVER-KIT

Oops, because your code implied you changed the slot from the default I imagined you were using slot 0. Sorry for throwing you that red herring!

Re: Critical Code section

Note that it's very hard to guarantee 100% precise CPU timings: you always run the risk of the other CPU, a DMA access, a lingering value in the CPU load/store unit or something else delaying a memory fetch and delaying your code. What issue exactly are you trying to solve? Chances are very large th...

Re: Aes CBC crashes

It's easier to say if you give the decoded backtrace. Either use 'make monitor' which will decode the backtrace automatically, or throw the backtrace hex addresses into addr2line.

Re: SD example crashs on ESP-WROVER-KIT

From memory, that slot shares pins with the SPI flash (given that you use a pre-existing module or board, or the default flash pins). Your code is (mostly) executed from that flash, so re-purposing those pins for something else is something the ESP32 doesn't quite like as all of a sudden it can't ac...

Re: Ethernet initialization error handling

You could copy the ethernet component to a components/ folder in your own project (so esp-idf prefers it above it's built-in ethernet component), and modify the emac_reset function there to have a fixed retry count... I'm not to familiar with the emac code to tell you if that would also make the res...

Re: What is "ets Jun 8 2016 00:22:57"

It's the sign-on message of the ROM; it's the first thing that gets printed after the ESP32 powers on and the CPU starts up. It means the ROM for the ESP32 was compiled on Jun 8, slightly past midnight, possibly by a set of tired colleagues happy they finally could go home. I think ets stands for Es...

Re: flash read err, 1000

GPIO12 is a bootstrap pin, the value read on power-up will set the flash working voltage. You may be running into something related to that.

Re: Documentation Error @ Technical Reference Manual Ch.11.5 I2C Registers

Yes, we are aware of this, a fix will be in a future revision of the TRM. Thanks for the note, however, it's always appreciated to get feedback. If you see more errors in the TRM, feel free to post them here and we'll pass them to the documentation team.
