esp32-h2 unresponsive after first flash with rust sdk

[gruvineo]

I tried Rust's development branch for esp32-h2 and after the first flash on this board https://pt.aliexpress.com/item/10050052 ... pt=glo2bra on the esp32-h2 chip, it stops appearing as a usb device on linux. This happened to 2 boards. I tried pressing reset, boot, plugging again, etc.

Did I do something wrong? I though it was a defect of the first board, but both behave like this.

Even if the firmware is not working, you should still be able to access the ROM bootloader (which handles USB communication for flashing). If this doesn't work, it may indicate that the flash process corrupted some important data.

can the flash process corrupt places other than the code, like the boot process? It happened to both boards...

it appears briefly as a usb device and then resets itself, every 5 seconds or something like that. On both devices it ocurred
