I have Wexler.tab 7200 with broken standby mode in sunxi kernel (in aw kernel suspend works). I have tried to debug standby code using RTC to trace it (i have no access to UART now), it hangs after this lines in dram.c: reg_val = mctl_read_w(SDR_DCR); reg_val &= ~(0x1fU<<27); reg_val |= 0x12U<<27; mctl_write_w(SDR_DCR, reg_val); in DRAMC_enter_selfrefresh (before suspend) I tried to replace standby binary with other, compiled from sdk. device now can enter standby mode, but kernel crashes (reboot) after resume. Does standby mode (not super standby) work on other A20 devices?
