Part Number: TDA4VE-Q1
Hi Expert,
We use J721S2 and PSDK8.4,
Currently our target board can display via DSI, And originally the AB26 & AD28 pin are configured to I2C.
After configuring AB26 & AD28 to the UART of A72 Linux, the user application access the UART linux device normally, but the DSI doesn't work well.
Are there any additional settings or any restrictions for this usecase ??
Regards,
Eten
Hi Eten,
DSI displays have a I2C interface that could be used for initializing DSI controller and touch. Below schematic is an example of the connection from TI's common processor board.
Most likely there is a resource conflict between UART and DSI on your board, so you would have to use different pins for either UART or DSI.
Regards,
Takuma
Hi Takuma,
Because our target board is connected another MCU to control DSI output panel, we don't need this I2C pins of DSI.
Is there a way to modify the DSI driver to disable the I2C control and then adjust the use of these pins, AB26 & AD28, from I2C to UART ?
Thank you !!
Regards,
Eten
Hi Eten,
If the DSI panel is connected to a different MCU and not to the TDA4VE, then changing pins on TDA4VE-side should not affect DSI behavior on the separate MCU.
Can you confirm whether on your schematic that DSI panel has no connections to TDA4VE?
Regards,
Takuma
Hi Eten,
Ah, I see. Thank you for the diagram. That clears up my misunderstandings.
Could you share dmesg logs for when the AB26 and AD28 pins are configured for I2C and DSI is functional? Additionally, could you share logs for when AB26 and AD28 pins are configured for UART and DSI is nonfunctional?
Regards,
Takuma

Hi Eten,
Comparing the logs, it seems there are no outstanding errors that are unique to pinmuxing for either UART or I2C. Two questions:
J721E, which is a similar platform to J721S2, has a board that has a DSI interface, and their device tree overlay for enabling that display can be found here:
I am expecting there to be some driver that configures your touchscreen through I2C, similar to many off-the-shelf DSI touchscreen as the one used by Beagle. So...
It seems strange that only I2C signals are routed to external MCU, since most DSI interfaces are connected via ribbon cable where all of the signals are sent to a single device. Unless, this was an intentional design choice and the MCU is running some sort of driver to configure DSI display through I2C.
Regards,
Takuma

Another question,
When enabling 2nd DSI driver, do you have the patch file for the module "psdk_rtos/vision_apps/utils/dss" ?
Regards,
Eten
Hi Eten,
For device tree, please only pinmux UART or I2C. I am not sure which will overwrite the other, but one pinmux will overwrite the other pinmux if the shared device tree is used as-is.
As for 2nd DSI driver, I assumed the Linux driver was being used for display, but could you clarify what/why patch is desired for the RTOS SDK instead of the Linux SDK?
Regards,
Takuma
Hi Takuma,
On the Linux side, we have checked the device tree and found nothing incorrect. So we suspect that something needs to be modified on the RTOS side. ( MCU2_0 is responsible for DSI driver )
In addition of to modifying the "J721S2_pinmux_data.c" of pdk package to disable I2C (AB26 & AD28), do any files need to be modified ?
As for 2nd DSI driver,
Sorry, I forgot to mention that we got a patch file to enable 2nd DSI driver by the following post.
So we needs the corresponding dss utils module patch to enable the 2nd DSI.
Thank you !!
Regards,
Eten
Hi Eten,
The below snippet of device tree looks incorrect:
main_uart3_pins_default: main-uart3-pins-default {
pinctrl-single,pins = <
J721S2_IOPAD(0x0c4, PIN_INPUT_PULLUP, 14) /* (AB26) ECAP0_IN_APWM_OUT.I2C1_SCL->ECAP0_IN_APWM_OUT.UART3_RXD */
J721S2_IOPAD(0x0c8, PIN_OUTPUT_PULLUP, 14) /* (AD28) EXT_REFCLK1.I2C1_SDA ->ECAP0_IN_APWM_OUT.UART3_TXD */
>;
};
main_i2c0_pins_default: main-i2c0-pins-default {
pinctrl-single,pins = <
J721E_IOPAD(0x0e0, PIN_INPUT_PULLUP, 0) /* (AH25) I2C0_SCL */
J721E_IOPAD(0x0e4, PIN_INPUT_PULLUP, 0) /* (AE24) I2C0_SDA */
>;
};
main_i2c1_pins_default: main-i2c1-pins-default {
pinctrl-single,pins = <
J721S2_IOPAD(0x0c4, PIN_INPUT_PULLUP, 13) /* (AB26) ECAP0_IN_APWM_OUT.I2C1_SCL */
J721S2_IOPAD(0x0c8, PIN_INPUT_PULLUP, 13) /* (AD28) EXT_REFCLK1.I2C1_SDA */
>;
};
Please remove main_uart3_pins_default or main_i2c1_pins_default. These both are changing registers at the same offset with different values of 14 or 13, so this will cause a resource conflict (aka, in the end, the register will either have UART or I2C, but not both as one will overwrite the other).
For the 2nd DSI driver, let me loop in Brijesh to see if he has some context.
Regards,
Takuma
Hi Eten,
Are you trying to enable second DSI instance in the Linux? Which patch are you using?
Regards,
Brijesh
Hi Eten,
But i think it is not yet supported in Linux or RTOS. so wondering how you are enabling second instance. Have you added support for it in the driver?
Regards,
Brijesh
Hi Eten,
Its not yet supported officially in the SDK, so will not be able to help much.
Regards,
Brijesh
Hi Eter,
The request is in the system, but the planning is not yet done and so planned date is not yet available. The main limitation is, its not possible to validated it on EVM.
Regards,
Brijesh
Hi Eten,
I still have not got the chance to check it with the team.
Regards,
Brijesh
