Re: Cannot wakeup from deepsleep

Same issue here with the ulp_adc example. The module just refuses to wake up. Also note the weird XTAL warning... ets Jun 8 2016 00:22:57 rst:0x1 (POWERON_RESET),boot:0x33 (SPI_FAST_FLASH_BOOT) configsip: 0, SPIWP:0xee clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00 mode:DIO,...

It would be nice if we could do these things as easily:

Re: [discovered] someone know what comes here?

My guess would be the esp32 version of the esp8285. The blue thing looks like a memory chip. Let's hope it is 4MB (probably not).

Re: Urgent Need for Pulse Width Measurement, Register/Hardware Descriptions Would Work

In components/driver/include/driver/rmt.h I see this line:

Code: Select all

rmt_rx.rx_config.idle_threshold = 0xffff;
Is 65.535 the upper limit of the idle threshold?

Re: Getting an error while receive a data continously through uart interrupt

Edit: after taking a better look at the code and the actual error, I think the problem is with this line inside test_my_uart uint8_t* data = (uint8_t*) malloc(BUF_SIZE); You are using malloc() without a free() when done. Try to test if allocating memory actually succeeds. (if data == null -> out off...

Re: Compiling openocd-esp32 on Raspberry Pi

I am currently using just the 'default' ms-vscode.cpptools. Maybe I just don't know what I am missing out on since my previous c experience is limited to the Arduino IDE. :oops:

Re: Compiling openocd-esp32 on Raspberry Pi

Oke, I adjusted the esp32.cfg file and OpenOCD is happy now. Using the Pi-Zero as an RNDIS/Ethernet Gadget, I can now run debug commands from Visual Studio Code on my W10 laptop. Thanks for the help!

Re: Compiling openocd-esp32 on Raspberry Pi

I changed the '__CLANG__' code in rtos_freertos_stackings.c to get it to compile with GCC. Unfortunately, after compilation I am running into the same problem as bbx10node in the original topic . The output is 100% consistent after several tries. Open On-Chip Debugger 0.10.0-dev-g90071eb-dirty (2017...
