ESP32-PICO-V3-02

[AndreyVinogradov]

Hello!
I'm new to ESP32 chips and I have some problems with flashing project to it. I successfully build and flashed 'hello world' test project to ESP32-DevKit-V4 based on ESP-WROOM-32D chip by using Espressif-IDE. And got nice prints.
But now I can't make any project work on ESP32-PICO-V3-02 chip on my own board. If I flash the same project to PICO via serial port, I got those logs:

I seems to have no errors during flash:

Before that I tried to build and flash "esp-at" project to PICO, but got about the same result. I looked in menuconfig and tried to switch on/off JTAG support in "security" settings. Don't know if it caused this behaviour.

What am I doing wrong? Is it PICO not compatible with IDF?

[ESP_Sprite]

That is odd behaviour. Can you post the schematic of your board? Perhaps there's something connected to the bootstrap or flash pins that makes it behave this way.

Connected to Cortex-M chip AT32F407 via ESP_RX/TX1 UART pins for AT-commands, RST/BOOT pins (I don't remember why BOOT was needed) and DBG for debug:

Currently I erased all program flash on AT32 so it's program would not interfere to work with ESP32.

external pins I use for flash/debug:

[ESP_Sprite]

That looks good. What is ESP_RST connected to, as in, do you properly reset the ESP32 on power-up?

[AndreyVinogradov]

I hold RST pin on 3.3V, and ESP32 chip run it's program. If I disconnect RST pin from 3.3V and leave it as is, something odd I see in logs:

Probably my biggest problem is that I don't know proper state of RST/BOOT pins... I think I tried all variations while booting/flashing project.

[ESP_Sprite]

The proper usage is:
- On power-on, after the power rails have stabilized, the reset NEEDS to be low for 50uS or more. If you don't do this, the ESP32 won't be reset properly and you'll get Weird Stuff.
- After this, the reset must be high. Don't tristate it, actively pull it high from your other MCU.
- If you need to reset the chip again, make the reset line low for >50uS, then high again.
- If, when the reset goes low->high, GPIO0 is low, the ESP will enter download mode. If it's high, it will try to boot from flash.

[AndreyVinogradov]

I tried to do as you say:
Channel 0 - Power supply
Channel 1 - Reset pin
Channel 2 - Boot (GPIO0) pin

First start power, next about 20ms after MCU initialized Reset and Boot pins and put them high (3.3V).

I also tried to toggle Reset pin high->low->high, hoping it will do:

Next I again flashed firmware with JTAG adapter and got the same result:

Another thing is that you connected IO10 to something. The Pico-V3-02 has embedded PSRAM at that pin and you shouldn't use it. Perhaps try again with the trace from that pin scratched through close to the Pico (to make sure high-frequency reflections aren't an issue)?

Aside from that, I'm having a hard time seeing what else could cause your issues, I'm afraid.

[AndreyVinogradov]

Thank you for your support. I will try to cut IO10 pin. I don't use it at all. Trace from that pin to AT32 is about 5cm. I also will try to unsolder and solder ESP32 to board again, may be some traces are not connected well.

[AndreyVinogradov]

Hello, again!

I managed to successfully flash test firmware via JTAG adapter and it worked. Looks like the problem was that bootloader did not fit in flash. I made partition table offset 0xA000 instead of 0x8000. And all went well.

But still there is a problem with flashing with UART adapter. Same firmware, same offset, but different result:

BTW, I'm not quite sure, what embedded flash size I should set. In datasheed told that there is 8 MB SPI flash. And JTAG-adapter find two flash banks:

Info : Using flash bank 'esp32.cpu1.flash' size 8192 KB
...

Can you give me working binary files and their offsets for tests so I could flash them both via UART and JTAG?

Also am I understand correct that there is a two "bootloaders" in ESP32? One at 0x1000 offset, which can be overwritten by JTAG and UART. And the other one, that can not, and it's somewhere else (0x00 offset maybe?), and it's purpose to flash firmware other UART.

Another thing is that if I take "fresh" ESP32-PICO-V3-02 and flashing it with UART, it works fine. But if I next flash it with JTAG, I can not flash it properly with UART anymore.
