Hi.

I disabled now the two options CONFIG_ESP32_WIFI_IRAM_OPT and CONFIG_ESP32_WIFI_RX_IRAM_OPT. With this there is enough space in the IRAM segment. According to the idf.py size-components the libc.a and libesp32.a need much more space in IRAM when the external PSRAM is enabled. Also the total ...

Hi.

I have a ESP32 project based on ESP-IDF branch /release/v4.0, which uses Wifi and BLE (Nimble stack). Until now I built the project with disabled external RAM and idf.py size-components gave the following sizes:


Total sizes:
DRAM .data size: 17816 bytes
DRAM .bss size: 49064 bytes

Hi Angus.

I (244) example: Mounting FAT filesystem

I only set the encryped flag in the partition table. But I do not think that enabling encryption via the bootloader would make it work, because the error


E (203) wl_flash: initSections(269): result = 0x00000104


points to the code at WL_Flash.cpp line 298/269

Hi all.

I took the wear_levelling example and set the encrypted flag on the storage partition:


# Name, Type, SubType, Offset, Size, Flags
# Note: if you change the phy_init or app partition offset, make sure to change the offset in Kconfig.projbuild
nvs, data, nvs, 0x9000, 0x6000,
phy_init, data ...
