Hi
Thank you very much for your reply.Later I test and add some log message into kernel source code by myself, print the message, I forget to say I connect the IPU-CSI interface to FPGA,and FPGA send a lot of generic data to the IPU and running on the GATED_CLK mode,run the driver and later the kernel is stop.It seems that really stop because i remove and reinstall the sdcard but the kernel was not active at all, it is the last runtime log message of the kernel below:
enter ipu_err_irq_handler().IRQ:37
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00000001
end ipu_err_irq_handler(),IRQ
enter ipu_err_irq_handler.IRQ:37
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x00000001
end ipu_err_irq_handler(),IRQ()
call ipu_dump_registers
imx-ipuv3 2400000.ipu: IPU_CONF = 0x00000101
I think it is not a hardware problem, according to the log message, we can see that the registers value,IPU_INT_STAT_10 is 0x1, refer to the manual, This bit indicates on an interrupt that is a result of a result of a Frame Lost of SMFC channel 0, and the IPU_INT_STAT_5 is 0x1, New Frame before end-of-frame error indication of Channel interrupt. This bit is the status bit of New Frame before end-of-frame error interrupt of Channel #n.
and I dump the ipu registers but no fully because the kernal is stop, I think the problem is my configuration error or mistake some config on ipu,but I think the kernel should not be stop. but i don't know how to fixed it, I search a lot of document but no found on google and baidu research, please help me, thank you very much.
