Hi, everyone, I use chip: arm64 a55x4(rk3568) root cell: linux (uart2 for console) non-root cell: rtthread (uart3 for console)
5 minutes after starting non-root cell, uart3 will get stuck. After a lot of tests, it was found that the clock of uart3 was turned off. In the rk3568 TRM manual CRU Register(Start Address: 0xFDD20000) CRU_GATE_CON28(offset: 0x370) sclk_uart3_en(Bit: 7) When excecute sudo io -4 -w 0xfdd20370 0xf0ff66 to uart3 will works again. So, things are almost clear. But, how to locate which program turned off the clock. Does anyone have relevant experience? -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
