Can you post the espflash v2 log? When espflash detects the board, it detects Flash size: 4MB. You can also use --flash-size 4mb arg, or use cargo espflash so it will use the partition table from your project: https://github.com/esp-rs/espflash/tree/main/cargo-espflash#bootloader-and-partition-table

My esp32c2 uses a 26M crystal oscillator, so the default baud rate is 74880, espflash v2 will be garbled when using "monitor" directly, so I have to manually set the baud rate of "monitor" to 74880, v3 fixes this problem, and will automatically set the baud rate of "monitor".

espflash monitor --baud=74880

espflash v3

in sdkconfig.defaults add CONFIG_XTAL_FREQ_26=y，cargo clean cargo run is ok!
but now only recognize 2MB space...App/part. size: 479,184/2,031,616 bytes, 23.59%，But can identify to Flash is 4MB

That problem is the crystal oscillator setting problem, has been solved. And I have to run cargo clean once. I set it before but didn't execute cargo clean, which not only didn't solve the problem, but also caused problems with espflash v2.

[SergioGasquez]

Can you try using cargo espflash flash --monitor? I've tried reproducing your issue with no luck.

❯ cargo generate esp-rs/esp-idf-template cargo --name issue614 -d mcu=esp32c2 -d advanced=false
❯ cd issue614/

Note how it fails but after appending CONFIG_XTAL_FREQ_26=y, doing cargo clean and rebuilding it then works

I also have this issue on esp32 (WT-ETH01), 2 works but 3 doesn't connect. CONFIG_XTAL_FREQ_26=y and cargo clean; cargo run does not resolve.

Mind trying to use --no-stub? You can add it to the custom runner command in .cargo/config.tom:

runner = "espflash flash --monitor --no-stub"

Or add it in the espflash command: espflash flash --monitor --no-stub target/riscv32imc-esp-espidf/debug/issue614-2

I'm still confused, as I was able to flash and monitor a 26 MHz C2 with no issues. Sadly, I don't have any ESP32, so I can't really try reproducing it.

Same result. I should mention my ESP32 uses a 40 MHz crystal, so I don't think that's related.

Chip type:         esp32 (revision v1.0)
Crystal frequency: 40MHz
Flash size:        4MB

When using the working espflash 2, does it also reports 40MHz ?? Do you know that for a fact or just guessing it from what espflash reports?
