Re: SDK Version question

Thanks for clarifying, I realise what happened now. The "--tags" option causes git to consult non-annotated tags as well as annotated. If you don't include this, git will only use annotated tags for the version. "v3.1-dev" is accidentally a non-annotated tag so it's not consulted unless you pass --t...

Re: How to use TCP_NODELAY with netconn to disable Nagle?

Hi jcsbanks, Just to make sure I understand: when you look at IP layer packet captures you see some TCP packets contain the results of multiple calls to netconn_send() or netconn_write(), yes? I think a 40ms delay is probably due to task timing rather than LWIP deliberating "nagling" the packets. Wh...

Re: SDK Version question

Hi fly135, Something odd seems to happen when you're running "git describe" manually. If I check out the same commit as you ("git checkout c97b8756f"), I get: $ git describe --tags --dirty v3.1-dev-449-gc97b8756f-dirty This matches what the build system is reporting, and appears correct (the tag v3....

Re: Uart smashing Wifi Stack

Hi jurstu, When you say the stack is being smashed, what's the basis for this? The example backtrace looks to have a valid call stack (in the WiFi ppTask). Do you get any warnings or errors from the Task or Interrupt WDT in your code? The oddest thing about the log output is that the device resets a...

Re: heap corruption inconsistency

Hi 0xffff, This had me scratching my head for a minute as well! The reason is that verify_fill_pattern() is swapping each word from 0xfefefefe (free memory) to 0xcececece as it goes through the memory region during allocation (uses one pass for performance), and even if it finds an invalid word it f...

Re: Debugging TG1WDT_SYS_RESET

I've split this discussion to a new thread to make it easier to find.

What version of ESP-IDF are you each using? For WiFi stack, a bug causing interrupt WDT resets was recently fixed.

If you have any sample code you can please post, this may help narrow it down.

Re: UART ISR not located in IRAM

Hi fasthands, No, I think this is just a chosen tradeoff due to the amount of code which needs moving to IRAM. We have some features coming in future IDF versions which will make it easier to configure which code is moved into IRAM, but you should be able to modify uart.c now to do this. Just take c...

Re: Secure boot and Flash encryption

Hi Chris, From the steps you've given, it sounds like you're doing everything correctly. Unfortunately there are a couple of issues (one long-standing, and one a recent regression on the master branch) that you've bumped into. And I get the following output when I have enabled "Verbose" output on (B...
