Problems with compile blue-retro

[parfuar]

Hi,
I'm trying to compile the BlueRetro code, I need to do some tests 😊.
A used espressif-ide-setup-2.10.0-with-esp-idf-5.0.2 (https://[dl.espressif.com/dl/esp-idf/](https://dl.espressif.com /dl/esp-idf/)) for windows 10.
when trying to compile, my first problem there is no file "brownout_ll.h" (main/startup.c), I tried to use a "brownout_ll.h" from the other project.
My second problem is in startup.c again at line 518 funcion "wdt_hal_context_t rtc_wdt_ctx = RWDT_HAL_CONTEXT_DEFAULT();",
"RWDT_HAL_CONTEXT_DEFAULT()" -> error: invalid initializer.

Probably the RWDT_HAL_CONTEXT_DEFAULT() initializer is done through a library, as the compiler gave an error I commented the lines (as I am doing tests).

Now I see these failures with IRAM. The size is larger than the available size.

Now my doubts. 😊

1 -Is the "brownout_ll.h" library really necessary? If so can you provide?
2- Function "RWDT_HAL_CONTEXT_DEFAULT()" is declares in a library? If yes, can you tell me which library it is?

With these corrections maybe it compiles the code correctly.

Thank you and congratulations for the project

You need to checkout and follow instruction from
https://github.com/darthcloud/BlueRetroRoot

You need to use same ESP-IDF version as I use.

Hey,
It's already working, thank you

Are the files that import to the board flash?

BlueRetro.bin (inside /build)
bootloader.bin (inside /build/bootloader)
partition-table.bin (inside /build/partition_table)

I became aware of this project because I saw several .bin files (image attached)
Were they made by you? if, yes? Is there any difference between them?

Thanks again 👍
