Part Number: AM5718
Other Parts Discussed in Thread: TMDXIDK5718
Tool/software: Linux
Hello, TI Experts,
Our customer sent us questions about VIP function of AM5718 below condition.
- PROCESSOR-SDK-LINUX-RT-AM57X 05_02_00_10
- EVM: TMDXIDK5718
They tried to connect "12bit gray scale sensor" to vin1a and vin2a.
And they would like to know how to modify the related files in Linux-RT-SDK.
They also checked the description of "9.4.4.3 VIP Slice Processing Path Examples" in the below TRM.
http://www.ti.com/lit/ug/spruhz7i/spruhz7i.pdf
But they cannot find any description for "12bit gray scale sensor" use-case.
Questions:
1:Could you tell us the recommended configuration values including like below setting to use "12bit gray scale sensor"?
VIPx_CSC_SRC_SELECT =
VIPx_SC_SRC_SELECT =
VIPx_CHR_DS_1_SRC_SELECT =
VIPx_CHR_DS_1_BYPASS =
VIPx_CHR_DS_2_SRC_SELECT =
VIPx_CHR_DS_2_BYPASS =
VIPx_RGB_SRC_SELECT =
VIPx_RGB_OUT_HI_SELECT =
VIPx_RGB_OUT_LO_SELECT =
VIPx_MULTI_CHANNEL_SELECT =
2: Those register settings are same as vin1a and vin2a.
Is this understanding correct?
3: They thought that the VIP setting is in "drivers/media/platform/ti-vpe/vip.c".
Is this understanding correct?
4: Are there any recommended modification files to use "12bit gray scale sensor" in Linux-RT-SDK
other than vip.c?
5: Are there recommended way to realize to marge vin1a and vin2a data into one picture by using
such as "9.4.8.7.1.1.6 Line Stride in TRM" function like below?
- Left half image is vin1a 12bit gray scale data.
- Right half image is vin2a 12bit gray scale data.
(Please refer attached pdf.)
We would also appreciate if you tell us the recommended way of realizing to marge" vin1a and vin2a 12bit gray scale data"
into one picture.
Best regards,
