Good news: I found the issue. Bad news which should probably be paid attention to by Espressif engineers: it's arguably a bug in esp_deep_sleep_start(). By reduction, I found that this was the line of code that caused the sleep current to increase to 995µA. (I'd previously reported 970, but it was a...

Joulescope. ISL9122AIINZ-T because low iQ Yes the mosfet design is fine. The next step is to destroy the pcb by removing the (smt) peripherals one by one. To date I have removed all the obvious things such as pull-ups, etc, but nothing that would be functionally destructive. The reason for this post...

Hello again. I am designing what will be a high-volume product that is based on the ESP32-S3-WROOM-1-N8R2. The design has relatively complex firmware, and a fairly simple hardware design of just a regulator and a couple simple i2c peripherals. It is existential that the design is able to achieve rea...

perfect. Once again, thank you @ESP_igrr !

My port is going well and I appreciate your responsiveness that is keeping me unblocked.

Now that I've got ESP32-S3 usb support implemented (thank you @ESP_igrr !), I've found that I have a minor challenge doing my debugging work using the wonderful JTAG-over-USB feature of the S3. Specifically, I've found that if I start openocd+gdb to debug over the usb-hosted JTAG, the tinyusb usb in...

I was unaware of this, and will try it immediately and will re-open this if necessary.

Thank you for your help and your responsiveness.

Getting me unblocked is truly appreciated.

Thanks. To be completely direct, I haven't ever used tinyUSB. My experience with USB to date has been on a different platform (stm32) which we're porting from. The thing that I love about esp-idf is that you folks are doing all the dependency management for me as a dev in a standardized way. Whether...

I'm designing the ESP32-S3 into a product and have made significant progress. I am at the point where I need to use the built-in hardware USB (pins 19/20) as the USB controller, in CDC ACM mode. (I cannot use the UART-based USB because that serial port is in-use for a different peripheral.) I've fol...

In case it helps to debug, when I do F1 "ESP-IDF: Monitor your device", the terminal displays: bash-3.2$ python /Users/rozzie/esp/esp-idf/tools/idf.py -p /dev/ttyUSB1 monitor Traceback (most recent call last): File "/Users/rozzie/esp/esp-idf/tools/idf.py", line 36, in <module> from idf_py_actions.to...

Hello. I am new to using vscode, and esp-idf under vscode, so I thank you in advance for your patience. By way of background, I'm using a Macbook Pro M1 Max. Today I did a clean install of vscode (1.64.2 Universal), and added extensions for PlatformIO (2.4.2) and Espressif IDF (1.3.0). I created a p...
