Error: espflash::connection_failed (ESP32 + ESP-Prog + JTAG) #450

systec-ms · 2023-07-24T14:53:06Z

Good day, I got an ESP32 D1 MINI, which I can program via espflash over the serial (micro-usb).
Additionally, I can flash the esp blinky example via the VSCode extension over the ESP-Prog JTAG connection (⚡️ Flashed Successfully (JTag)).

However, if I try to flash my rust code via espflash over the EPS-Prog JTAG connection, I run into Error: espflash::connection_failed.

I would appreciate any help, thanks in advance.

Could it be that it is not possible to flash Xtensa chips via espflash and jtag (#23)?

If so, how do I extract the bootloader.bin, partition-table.bin and binary.bin to flash it via openocd?

systec-ms · 2023-07-31T06:24:36Z

The following works for me:

Flash via ESP-PROG (JTAG)

Erase

openocd-esp32openocd -f /usr/share/openocd-esp32/scripts/interface/ftdi/esp32_devkitj_v1.cfg -f /usr/share/openocd-esp32/scripts/target/esp32.cfg -c "init; reset halt; flash erase_address 0x1000 16773120; exit"

Flash Bootloader

Use fd bootloader.bin --no-ignore to find bootloader.bin location (build by esp-idf-sys).
Typical locations are (note esp-rs/esp-idf-sys#97):

target/xtensa-esp32-espidf/debug/build/esp-idf-sys-5088a6f49af329e1/out/build/bootloader/bootloader.bin
target/xtensa-esp32-espidf/release/build/esp-idf-sys-0f6f63297e12c38d/out/build/bootloader/bootloader.bin

openocd-esp32openocd -f /usr/share/openocd-esp32/scripts/interface/ftdi/esp32_devkitj_v1.cfg -f /usr/share/openocd-esp32/scripts/target/esp32.cfg -c "program bootloader.bin 0x1000; exit"

Flash Partition Table

Use fd partition-table.bin --no-ignore to find partition-table.bin or use espflash partition-table --to-binary to export the partition-table binary.

Typical locations are (note esp-rs/esp-idf-sys#97):

target/xtensa-esp32-espidf/debug/build/esp-idf-sys-5088a6f49af329e1/out/build/partition_table/partition-table.bin
target/xtensa-esp32-espidf/release/build/esp-idf-sys-0f6f63297e12c38d/out/build/partition_table/partition-table.bin

Export binary:

espflash partition-table --to-binary --output partition-table.bin .embuild/espressif/esp-idf/release-v4.4/components/partition_table/partitions_singleapp.csv

Flash binary:

openocd-esp32openocd -f /usr/share/openocd-esp32/scripts/interface/ftdi/esp32_devkitj_v1.cfg -f /usr/share/openocd-esp32/scripts/target/esp32.cfg -c "program partition-table.bin 0x8000; exit"

Flash Application

Export binary (change /debug/ to /release/):

espflash save-image --chip esp32 target/xtensa-esp32-espidf/release/app app.bin

Flash binary:

openocd-esp32openocd -f /usr/share/openocd-esp32/scripts/interface/ftdi/esp32_devkitj_v1.cfg -f /usr/share/openocd-esp32/scripts/target/esp32.cfg -c "program app.bin 0x10000 reset exit"

Should be verify reset exit but verify is currently unsupported

SergioGasquez · 2023-10-06T07:06:16Z

Hi! Sorry for the late reply, Can try using #487 and see if it solves the issue? You should be able to flash Xtensa via JTAG

SergioGasquez · 2023-11-16T08:44:29Z

Hi! Would you mind verifying if the issue still persists with the changes on main?

cargo install espflash cargo-espflash --git https://github.com/esp-rs/espflash

systec-ms · 2023-11-16T10:21:24Z

Sorry for the late replay, sadly no luck:

❯ espflash -V

Same result with espflash flash --monitor target/xtensa-esp32-espidf/release/blinky.
Flashing still works with:

openocd-esp32openocd -f /usr/share/openocd-esp32/scripts/interface/ftdi/esp32_devkitj_v1.cfg -f /usr/share/openocd-esp32/scripts/target/esp32.cfg -c "program target/app.bin 0x10000; reset; exit"

So unfortunately, the problem still exists.

SergioGasquez · 2023-11-20T15:08:25Z

Have you tried to flash your application with esptool?

SergioGasquez · 2023-11-23T16:42:40Z

#521 may fix this issue, mind testing again with main?

cargo install espflash cargo-espflash --git https://github.com/esp-rs/espflash

Sorry for the debugging procedure, but since I can't reproduce the issue, I would like to know if it's still there

systec-ms · 2023-11-24T07:17:22Z

Sadly, same result as before.

SergioGasquez · 2023-12-12T10:00:46Z

Have you tried to flash your application with esptool?

Hi! By any chance, did you try esptool?

systec-ms · 2023-12-12T11:01:47Z

Have you tried to flash your application with esptool?

Hi! By any chance, did you try esptool?

I tried it initially, and it worked, but never again since.

SergioGasquez · 2023-12-29T08:04:30Z

Do you have anything connected into the strapping pins?

systec-ms · 2024-01-10T09:34:43Z

Sorry again for the late reply, but I no longer have the hardware available, so feel free to close this issue.
