Hello.
I'm using TDA4 EVM board and porting our camera sensor to EVM.
I found some issue relate MIPI-CSI HS-settle time.
Below table is i tested in the TDA4 EVM board and case of HS-prepare+zero time is under 160 ns (case-3,4), any frames not received from MIPI-CSI.
It will be relate to HS-settle time and it looks like approximately 160 ns or some below.
In the MIPI-Dphy specification, HS-prepare+zero time is more longer than HS-settle time.
| case-1 | case-2 | case-3 | case-4 | |
| HS-prepare time (ns) | 41.1947 ns | 53.4 ns | 47.4074 ns | 45.9737 ns |
| HS-prepare + zero time (ns) | 170.09 ns | 160 ns | 152.407 ns | 152.168 ns |
| MIPI-Dphy clock speed (Mbps) | 837 Mbps | 600 Mbps | 540Mbps | 837Mbps |
| TDA4VM EVM result | Success | Success | FAIL | FAIL |
| TDA2PX EVM result | Success | Success | Success | Success |
So, I want to know what is TDA4 EVM's MIPI HS-settle time ?
And it can be modified in the PSDK code ?
Thanks and Regards.
