I've run some tests with the following 2 Kirkwood boards: Cloud Engines Pogo V4 88F6192 (with CONFIG_DM_RTC and CONFIG_RTC_EMULATION), and Marvell Sheevaplug 88F6281 (with CONFIG_DM_RTC and CONFIG_RTC_MV). It seems that it was either frozen or the timer did not expire at some subsequent sleep commands. Sometime it happened at 2nd command, some time at a later sleep command. For example, === Pogo V4 (the 1st sleep command works correctly at 10 seconds on my stopwatch) U-Boot 2022.10-rc3-00048-g66ccd87a9c-dirty (Aug 30 2022 - 13:38:24 -0700) Pogoplug V4 Hit any key to stop autoboot: 0 Pogo_V4> sleep 10 Pogo_V4> sleep 31.5 <frozen here> === Sheevaplug (RTC battery is old, so the date was not updated, but the clock seems OK) U-Boot 2022.10-rc3-00048-g66ccd87a9c-dirty (Aug 30 2022 - 14:14:24 -0700) Marvell-Sheevaplug Hit any key to stop autoboot: 0 => date Date: 2000-01-01 (Saturday) Time: 0:02:55 => sleep 10 => date Date: 2000-01-01 (Saturday) Time: 0:03:18 => sleep 10 => sleep 20.1 <frozen here> Please let me know what I can do (i.e. perhaps running a debug patch).
