Re: ESP32S3 Custom bootloader

Unless if i update the build structure as below, then it is compiling without error. Because the CMakelist.txt inside bootloader/subproject is referring custom bootloader path as "${PROJECT_SOURCE_DIR}/bootloader_components". ├── main │ ├── CMakeLists.txt This is main cmakelist.txt and it references...

ESP32S3 Custom bootloader

Team, I have copied bootloader folder from <esp_sdk>components to myproject/components. I modified the necessary changes so that it can generate pbl.bin in build/pbl/pbl.bin. But i could not avoid generating bootloader.bin. The assumption is to use this customized pbl.bin instead of bootloader.bin. ...

The same example in my custom target consumes 8mA. If the valu...

Re: ULP current consumption with SIP 8MB

With deep_sleep example which you specified also i see same 8mA current consumption. The sleep wakeup source in deep_sleep example which i used is ext0. In ulp_riscv/gpio example wakeup source is ulp. I can see the different wakeup sources (using esp_sleep_get_wakeup_cause()) with same reason (DSLEE...
