Any plans to support PSRAM for ESP32-S3? It's an important feature for this platform.
@lgl88911 Octal PSRAM should be available when Zephyr starts supporting hal 5.1 - we are taking care of some regressions to make it usable as 'pre-alfa' in order to share a WIP / Draft PR.
Hey, is this still the latest status?
@laurin yes, it is. We are wrapping up the last issues on hal5. You can try the current wip: https://github.com/zephyrproject-rtos/zephyr/pull/65942
This is the PR https://github.com/zephyrproject-rtos/zephyr/pull/68760 for hal 5.1 that ended up being merged.
So, is this issue still valid? How would you enable it if you were using 3.7?
PTAL CONFIG_SPIRAM_MODE_OCT
https://docs.zephyrproject.org/latest/kconfig.html#CONFIG_SPIRAM_MODE_OCT
You also need to enable PSRAM normally and do all other proper configurations.
Even though the implementation has bugs, I think this can be closed.
Currently it is not possible to use the ESP32S3 variants with 8MB PSRAM. See issue #64510. For me it breaks the use of PSRAM on the XIAO ESP32S3 boards I want to use.
The solution would be to be able to use PSRAM with octal spi.
