According to the Radxa E52C Schematic [1], both the i2c5 bus and the hym8563 chip are marked as NC. Remove them to avoid the following log: rtc-hym8563 5-0051: could not init device, -110 rtc-hym8563 5-0051: probe with driver rtc-hym8563 failed with error -110 [1] https://dl.radxa.com/e/e52c/hw/radxa_e52c_v1.2_schematic.pdf
V1.209 and later should have RTC. What version do you have? Best regards, -- FUKAUMI Naoki Radxa Computer (Shenzhen) Co., Ltd.
