Hi everybody,

For one of our products we decided to switch esp-idf from v3.3.4 to v4.2.
I installed all new toolchains and created a new project, setup cmake, configured SDKCONFIG trying to have the same options (or at least I think so) as the previous one: I have onlyremoved "Heap memory debugging" and disabled options for WiFi IRAM optimization (otherwise I have problem of IRAM0 overflow).

After compilation I discovered a big increase in size of the bin file. Just to compare:

esp-idf V3.3.4

Code: Select all

Total sizes:
 DRAM .data size:   18384 bytes
 DRAM .bss  size:   47424 bytes
Used static DRAM:   65808 bytes (  58772 available, 52.8% used)
Used static IRAM:  124313 bytes (   6759 available, 94.8% used)
      Flash code: 1156481 bytes
    Flash rodata:  250232 bytes
Total image size:~1549410 bytes (.bin may be padded larger)

esp-idf V4.2

Code: Select all

Total sizes:
 DRAM .data size:   22760 bytes
 DRAM .bss  size:   68208 bytes
 DRAM other size:      12 bytes (.noinit)
Used static DRAM:   90980 bytes (  33600 available, 73.0% used)
Used static IRAM:  101011 bytes (  30061 available, 77.1% used)
      Flash code: 1365283 bytes
    Flash rodata:  293960 bytes
Total image size:~1851234 bytes (.bin may be padded larger)

A difference of about 300Kb!!

Source code are the same, except for modification of the new WiFi init which requires "esp_netif_init" instead of "tcpip_adapter_init".

Is there any guide for "safe" migration from esp-idf v3.3 to v4.2?
Or any hint to follow?

Thank you!

idf.py size-components should give you more info

Thanks @WiFive. I have worked on menuconfig and removed some BLE features (in particular debug to save .bin size), so now I have a difference of 100KB. Below is size-components:

The only main difference is the presence of " libmbedcrypto.a" which account for 83KB.
I'm also checking why "libmain.a" (my application code, righe?) is about 10KB respect previous version more even if code is the same.

Thanks

Thanks @boarchuz. I have checked difference and, although there is an increase in some of my source code(this is strange but could be related to change from "tcpip_adpater" to "esp-netif"? ), the main and relevant difference is the presence of the libmbedcrypto.a library which account for 83KB.

But I think to have selected the same options in the menuconfig so to mantain the same functionalities. Below the difference.

Thanks

libmbedtls.a also decreased by that amount.

Total image size:~1650794 bytes (.bin may be padded larger) 1598298 +52496
