It seems my erase and write process is working well, but when I get to the end I get the following: E (114474) esp_image: Segment 1 has load address 0x3f400010, conflict with segment data at 0x00118010 E (114661) esp_image: Segment 7 has load address 0x400d0018, conflict with segment data at 0x00148...

I2C, or SPI, or UART.

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...

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

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_...

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.'

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!

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!

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...

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?
