DS90UB964-Q1: buffer_Error

Xiao Zhu2
Part Number: DS90UB964-Q1
hello team
When DS90UB964 used Internally Generated FrameSync and find buffer_ERROR. It seem the occure overflow. Does 964 have registers check the the root cause or do you give some comment that i can debug to find the root cause? thanks

Hi Xiao,
Buffer error means your input is higher than your output. Try to set the CSI output rate higher or reduce your CSI input rate and see if it resolves your issue.
Best,

Hello Jiashow
When not use internal FrameSync, the buffer error is diappear. Attached is the register setup. So could you give more comment about it?

Hi Xiao,
In your code I don't see the FrameSync signal being outputted on the serializer side. Is that intentional? Do you only intend the output the FrameSync to deserializer GPIO0?
What's the duty cycle of the FrameSync you intend to use? You are using back channel 50MHz right?
Just wanted to make sure these registers are programmed correctly:
[ 39.460577] == 964 Write Reg[0x19] = 0x01
[ 39.461068] == 964 Write Reg[0x1A] = 0x4D
[ 39.461558] == 964 Write Reg[0x1B] = 0x0B
[ 39.462050] == 964 Write Reg[0x1C] = 0xB7
For the default BC Freq of 50MHz, Frame period = 600 ns --> 27778 counts:
For a 50% duty cycle, set high time & low time to 13889 -> (0x3641)
Could you try this and see if your issue disappears?
Best,
Jiashow

Hello Jiashow
The 964 back channel freq default is 2.5Mhz. 964 used refclk is 24.96Mhz, so the back channel should be 2.496Mhz. the serializer used 4 933. and the frame is 25Hz. So based on this , how to setup the four register?

Hi Xiao,
Based on the back channel, the frame period is ~12us. If the FrameSync frequency is 25Hz, then the total count is (1 sec / 25Hz) / 12 us = 3334
For FrameSync of 25Hz with duty cycle 50%. Try setting reg 0x19 - 0x1C to the following:
FS_HIGH_TIME_1: 0x06
FS_HIGH_TIME_0: 0x83
FS_LOW_TIME_1: 0x06
FS_LOW_TIME_0: 0x83
For FrameSync of 25Hz with duty cycle 10%. Try setting reg 0x19 - 0x1C to the following:
FS_HIGH_TIME_1: 0x01
FS_HIGH_TIME_0: 0x4D
FS_LOW_TIME_1: 0x0B
FS_LOW_TIME_0: 0xB9
Best,
Jiashow
