Possibly a duplicate of #135410. |
|
#135410 should already be fixed on nightly tho 🤔 |
|
Hmm, you're right, that is indeed strange |
|
I am pretty sure OP is using a fork of rustc, so I truly have no idea what the version string means. Our in-tree xtensa targets are broken, so the relevant community has been using a fork. See https://docs.esp-rs.org/book/installation/riscv-and-xtensa.html which is linked from one of the links posted in the issue description. |

@saethlin, you are right. I will close this issue. My bad, i'm kind of new in embedded Rust. For the STM32 environment I use the Rust toolchain, and I forgot that Espressif indeed forks their toolchain/compiler |

I've added my code as a zip file to this ticket.
Only been using Rust for a few years in hobby projects. So I can answer superficial questions.
Keep in mind, it is written for embedded hardware. I was trying to implement a SPI display.
To run code: Follow the installation guide of the ESP-Rust book.
Crates used are esp-hal & mididsi
