linguini1 opened a new issue, #16951: URL: https://github.com/apache/nuttx/issues/16951
### Description / Steps to reproduce the issue The current SPI driver doesn't work with the listed alternates in the BCM2711 peripheral datasheet. Only SPI0 currently works, as SPI3-6 needs magic registers to be configured before they can work. In the Linux supported version, this is done by the Linux driver. Even with the correct dt-overlay file from the Raspberry Pi foundation's repository, the alternate interfaces are not enabled. The source code of other implementation may need to be examined to locate these registers. ### On which OS does this issue occur? [OS: Linux] ### What is the version of your OS? Arch Linux 6.6 ### NuttX Version master ### Issue Architecture [Arch: arm64] ### Issue Area [Area: Drivers] ### Host information _No response_ ### Verification - [x] I have verified before submitting the report. -- This is an automated message from the Apache Git Service.
