Size overflow issue in IRAM: Not enough place for my own program <SOLVED by Angus>
Posted: Tue Jul 13, 2021 10:22 am
Hi there,
I've find out that when I try to use RainMaker with my epaper Firmware, using a display buffer bigger than 80/100Kb is already giving me problems. When I do idf.py build
/home/martin/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: region `iram0_0_seg' overflowed by 25320 bytes
If I see this correctly is failing since it's about 25 Kb too big. So it's not about RAM since I'm initializing the _buffer directly in PSRAM:
This problem is gone if I compile this on a branch without RainMaker WiFi provisioning. My question is: There is any way to place BLE libraries directly on PSRAM or similar?
I see an option that compiles WiFi libraries in SPI Ram but it does not make any difference. Is still giving the same overflow in the build process after checking that option in idf.py menuconfig
Any ideas how I can solve this?
Just as a reference, this is the CPP file that is my main program:
https://github.com/martinberlin/cale-id ... r-wifi.cpp
For further info this are my partitions:
And here the report from make size-components
