UPD: controller restart was not an issued. It was logs, that I enabled in my console. I duplicate data from Rx/Tx AT-UART port to other Debug-UART Tx port to listen AT-commands work. And somehow it affects the AT-UART work. I don't have any ideas right now, but that Debug logs only slowing down cont...

UPD: just restarted ESP32 chip, and successfully uploaded 29379 bytes file. Nice, will continue testing with larger files.
I noticed that this time +IPD splits data on different size chunks: 2920, 2115, 1440 and 2840 bytes.

Hi, I updated esp-at project with last changes (commit 409a018561105) including commit 73fcea9f17518 I also updated esp-idf version: branch:release/v4.3 commit:844624ead2b204639f6cedaaf0f31902373022f8 problem is still there. ESP32-Pico-v3-02 send more bytes than it declares in +IPD. Can you please, ...

Hi! I'm having a problem with +IPD command. It shows wrong number of bytes to read. My ESP32 chip connected to MCU with UART I'm trying to download a file about 20-30kB size. When I do that I receive: +IPD,<ID>,<N>,<ip addr>,<port>:<N + M data bytes> +IPD,<ID>,<N>,<ip addr>,<port>:<N + L data bytes>...

I see, thank you. But I still don't understand why after flashing via JTAG project stop flashing with UART. Probably the problem is not in bootloader size, but something else. I'm still trying to flash ESP-IDF-AT project to PICO, but the program always crushing at start. The same AT project I loaded...

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 f...

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.

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). esp32_02.png I also tried to toggle Reset pin high->low->high, hoping it will do: esp32_01.png ...

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: ... rst:0x1 (POWERON_RESET),boot:0x1 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_REO_V2)) wai▒ets Jul 29 2019 12:21:46 rst:0x1 (POWERON_RESET),boot:0x1 (DOWNLOAD_BOOT(U...

ESP32-PICO: 2022-06-27_09-42-12.png 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: 2022-06-27_09-57-41.png Currently I erased all program flash on AT32 so it's program would not interfere to work w...
