IRAM usage rising, especially libbtdm_app.a

[ErikCorry]

When updating the Toit platform to the latest esp-idf 5.0, I notice that the IRAM usage has been increasing over the board.

See the changes from March to today at https://gist.github.com/erikcorry/f44c6 ... 89ab40b9dd

One big culprit is the bluetooth stack. Is there a way to make it use flash instead of IRAM? 30k is a lot of memory on a limited system.

My sdkconfig is at https://gist.github.com/erikcorry/ed93e ... b8feed4d12

I second this

Some of my boilerplate test apps which only provision over BLE sometimes run out of IRAM, without even adding any app logic

Using esp-idf 5.1.1

Same for me!

No answer so for?! What is going on? Here is my feedback!

I don’t know what you crazy guys at ESP are doing !!? I was about to migrate my project from IDF 4.2 to IDF 5.2. I encountered that even your libraries including wifi+BT do not compile because IRAM gets exhausted! I mean, are you totally dumped! You are dealing with a resource constrained device and offer such a crappy library!! I mean, from where are you sourcing your engineers? Directly from high school? Do you ever test this?
Furthermore, CMAKE is a pain! I liked the gnu make, worked out of the box. Now you need to declare all the dependencies. What a shit and what a pain! Device configuration is a pain to get optimized performance. Currently in need a solution to fix this issue:
Used static IRAM: 140074 bytes ( -9002 remain, 106.9% used) Overflow detected!

Now, you crazy guys tell me how to fix this! But, don't tell me I need to enable the extra IRAM#1 to get another issue on runtime heap allocation!
