Unusual, that only the RTC driver was left out for piCore v13.1, but was posted for piCore64 v13.1. Are the release builds done by hand for each platform/target, namely ARMv6, ARMv7, ARMv7l, and ARMv8 or is it scripted for each of the 32-bit and 64-bit targets? Not that it is important, just found the inconsistencies between each release as application testing is being performed. Consideration for LTS kernel migration to address the numerous CVEs to date, going back to v13.x, but may drop off since kernel 5.10.x is expected to be EOL'd anytime soon after the next LTS kernel 7.x is announced.
