Link failure with BT (CON-1149)

[jonsmirl]

I just updated my esp-matter and I can't link. This is because I am allowing BSS in external memory

I need this fix before I could link again

If you are having problems at link time, can you try removing the following lines from the component/bt/linker.lf file:

    if ESP_ALLOW_BSS_SEG_EXTERNAL_MEMORY = y:
        * (extram_bss)
and try compiling again.

This is something that is broken in IDF and we somehow pulled this in when updating the connectedhomeip submodule to fix crashes during ble-deinit sequence.

Can you please try to disable ESP_ALLOW_BSS_SEG_EXTERNAL_MEMORY for short run? This will be fixed in next IDF release or I'll check how this can be fixed in connectedhomeip.

I am also having same issue with light_switch example .. i am new to such big build systems, can someone point towards the right file to fix. Where should i define this ESP_ALLOW_BSS_SEG_EXTERNAL_MEMORY to 0 ?

EDIT:
Got the symbol from search in menuconfig

[shubhamdp]

This is fixed with esp-idf v5.2.2, can be used with CONFIG_ ESP_ALLOW_BSS_SEG_EXTERNAL_MEMORY=y. Please close the issue if resolved.

Closing it now. Please re-open if you see this
