We get a crash in the v3.1 (or v3.2) bootloader when attempting to jump to the v3.3-rc application.

Note that if I upgrade the bootloader to v3.3-rc, it works fine.

Is there any known incompatibility here? I can try reproducing with a minimal example if that helps.

Is bond 2 with esp32 shipping now or still mt7688 version?

Hi Chris,

Sorry for the inconvenience.

This regression (older bootloder + DIO mode + PSRAM can't boot) should be fixed in the latest release/v3.3 branch commit, so suggest checking out that branch and pulling the latest (a few commits have been pushed since v3.3-rc). It will be fixed in the final v3.3 release, also.

Angus

Thanks Angus! So, was my mistake to use the tag v3.3-rc rather than the latest on the branch.

WiFive: see the beta forum post here: https://forum.bondhome.io/t/bond-v2-platform/466 The units with serials starting ZZ are ESP32-based.

You should sell bare board without firmware to use as esp32 universal IR/RF dev kit.
