Re: Debugging ESP32 programs on Linux using an "ESP32 Emulator Library"

There hasn't been any progress on this, i'm afraid. Other things are currently having higher priority. Although some of this will become easier as a side effect of the ongoing code refactoring for multiple target support.

Re: eMMC module

If you disable the DDR mode in sdmmc_host_t::flags, does this change the error pattern? The interesting thing seems to be that the write command seems to succeed in 4-line mode, but read command fails in 4-line mode. I can't really explain how this may happen, as any signal issues should be symmetri...

Re: Read registers using C code?

For these registers you should use DPORT_REG_READ macro. If you still have a compilation error when using DPORT_REG_READ, please post the error here. If all the registers of a peripheral read back as 0, then it might mean that you haven't enabled clock for the peripheral and taken it out of reset. S...

Re: ULP wake using ext1

No, waking up the ULP using an IO isn't possible.

ULP can periodically poll the state of the IO, so depending on the expected pulse width you can find suitable polling frequency.

Re: ESP32 - combining timer AND GPIO wake up

If I understand your problem correctly, you wish to wake up only after certain number of pulses from the sensor, and not on each pulse?
If so, please check the "system/ulp" example in IDF. It demostrates how to do pulse counting using ULP coprocessor, and wake up after given number of pulses.

Re: v3.2 make menuconfig for component NVS is empty.

Some options related to NVS encryption will show up there if Flash Encryption feature is enabled under "Security settings". Please read the Flash Encryption documentation before doing it though!

Re: First Firmware Writing of ESP32-D0WDQ6

Yes, first time firmware upload is no different from the rest, and can be done over serial port ("make flash" or "idf.py flash", if using CMake build system, or using esptool.py). ROM bootloader responsible for serial uploads is always present on the chip and cannot be erased.

Re: Encrypted flash and SPIFFS storage together?

No, they aren't mutually exclusive. FATFS is compatible with flash encryption, both with wear_levelling and without. When FATFS is read-only, it can be used without wear_levelling. When it is used for reading and writing, it should be used together with wear_levelling.
