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

Closed systec-ms closed 9 months ago

systec-ms commented 1 year ago

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 (https://github.com/esp-rs/espflash/issues/23)?

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

systec-ms commented 1 year ago

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 https://github.com/esp-rs/esp-idf-sys/issues/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 https://github.com/esp-rs/esp-idf-sys/issues/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

Hi! Sorry for the late reply, Can try using https://github.com/esp-rs/espflash/pull/487 and see if it solves the issue? You should be able to flash Xtensa via JTAG

SergioGasquez commented 10 months ago

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

Sorry for the late replay, sadly no luck:

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.

Have you tried to flash your application with esptool?

SergioGasquez commented 10 months ago

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 commented 10 months ago

Sadly, same result as before.

SergioGasquez commented 9 months ago

Have you tried to flash your application with esptool?

Hi! By any chance, did you try esptool?

systec-ms commented 9 months ago

Hi! By any chance, did you try esptool?

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

SergioGasquez commented 9 months ago

Do you have anything connected into the strapping pins?

systec-ms commented 9 months ago

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