Re: Device quick connect

I2C, or SPI, or UART.

Re: OTA of factory app

How do you instruct the tool to use OTA0 as the factory flash location? I put the correct offset into menuconfig, but I still get this: I (12) boot: compile time 03:25:01 I (13) boot: Enabling RNG early entropy source... I (13) qio_mode: Enabling QIO for flash chip ISSI I (14) boot: SPI Speed : 80MH...

Re: Crash issues with WiFi

Thanks for the clues. I will do some more analysis. This is basically powersave example plus GPIO setup, one UART, and LED intensity variation.

Crash issues with WiFi

I keep getting this crash, even just using WiFi station mode. I'm using essentially the same code as the WiFi powersave example. Thoughts? I (12) boot: ESP-IDF v2.0-rc1-725-g07b61d54 2nd stage bootloader I (12) boot: compile time 00:14:16 I (13) boot: Enabling RNG early entropy source... I (13) qio_...

Re: ESP32 interrupts during flashing

The flash process seems to be pretty time-critical. If I don't have a perfect electrical connection when it starts it will never start, for instance, have to ctrl-c and restart 'make flash.'

Re: Needed additional pins for PSRAM

Does this mean GPIO9 and GPIO10 can be used instead of GPIO16 and GPIO17? Also, are the pins physically wired or can the GPIO matrix be used to switch out the pin functions? Thanks!

Re: GPIO16/17 initialization issues

Ok, because 16 &17 aren't used by the D0WD for flash communication. Are any of the VDIO power domain pins available as GPIOs on D2WD? Thanks!

GPIO16/17 initialization issues

I'm getting a crash when I do the following: #define SETGPIO(num) \ gpio_set_direction(num, GPIO##num##_MODE); \ if (GPIO##num##_MODE == GPIO_MODE_OUTPUT || GPIO##num##_MODE == GPIO_MODE_INPUT_OUTPUT_OD) \ gpio_set_level(num, GPIO##num##_LEVEL); \ gpio_set_pull_mode(num, GPIO##num##_PULL); \ if (GPI...

Re: VDD_SDIO for ESP32 D2WD

What happens if we don't do this? I have been running for several days on a proto board without issue..., with MTDI left floating. What is the consequence?

Re: ESP32 Pin Layout (for QFN 5*5), Pin25, Pin26

This matches our PCB design as well, which is good because it's being assembled now. :)
