Re: idf.py erase_flash doesn't work

I know that most flash chips have configuration registers that can write-protect some or all of the flash memory. You can read those registers using 'esptoool.py read_flash_status'. Perhaps if you compare the results of that to the datasheet of whatever flash chip you use, that may lead to the reaso...

Re: HCI UART over UART0 (One UART for flashing and HCI Bluetooth)

Just to double-check: what are the actual pins you decided on using?

Re: esp32s2 i2s parallel mode

Hard to say. How did you configure your I2S peripheral? What hardware are you using to measure this?

Re: starter project - a question about implementation

You would use a mutex for that. If it fits you can also use an atomic variable to store your data (you're limited to 32 bits then, though), in which cases no mutexes are needed.

Re: Can't really help anyoen - the idf-openocd debugger don't work

Well, openocd works like a charm - that looks like a good JTAG connection. However, I'm not sure what you have connected to OpenOCD but it looks like that is expecting an ARM CPU somehow, not an Xtensa. Are you sure that whatever you're trying to do the debugging with supports and is configured for ...

Thanks, so you're effectively making the led_strip thing into a component. Do you also have a CMakeLists.txt in that directory? If so, can you post its contents?

Re: ESP32-S2 module custom programming

Also, what specifically is that block labeled 'ESP32-S2'? The chip? A module (if so, which)? A devboard (if so, which)?

Re: ESP32-S2 module custom programming

That could be anything between the USB-to-serial chip and the ESP32, I'm afraid. Do you have a schematic of your current setup?

Re: One byte in ESP32 flash memory is broken!!!

Can you give us a bit more information? - What hardware are you using specifically? What's the power supply like? What specific version of Wroom are you using, with what amount of flash? - What environment is the product used in? Anything like high temperatures, EMC, ... that could be a risk? - What...

Re: ESP32-PICO-KIT Where and what are pin out numbers for SPI devices?

Note that (unless you need to drive the SPI at high speeds >26MHz) you can use the GPIO matrix to route the signals to most any pin.
