DRA821U: Request for Pin configuration

Hi,

Could you please provide pin configuration for DRA821.

Can you please share more details about what you are looking for ?

Pin description available from Technical Data sheet (TD) of SoC along with PAD CONFIG address to configure pin with required functionality. Please refer to TD once.

Hi,

We need pin configuration file.

You can refer to the Sysconfig tool for the pin configuration of DRA821.

Hi Sudheer,

We’re looking for a blank pin configuration file.

Although the SysConfig tool is typically used for pin configuration, we don’t require it in this case. All we need is the pinout information—similar to what’s provided in the device datasheet.

There is no specific configuration file available for all pins. Sysconfig generates output files based on the pins selected.
We are the generated files from Sysyconfog in the TI RTOS SDK for MCU cores for configuring the pins. Similarly, device tree updates are taken for configuring pinmux from HLOS, like Linux.

Hi Sarthak,

Seconding Sudheer's comment. The DRA8x device does not have a pinout list that is similar to the file you shared. This is because most of the pins on the SoC is muxed between different functionality. So pin functions are determined only at runtime, and by customer.

As an example from datasheet (https://www.ti.com/lit/ds/symlink/dra821u.pdf?ts=1758030322496&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDRA821U), a single pin, U3, depending on the value of the PADCONFIG register, can be one of the following:

• ECAP0_IN_APWM_OUT
• SYNC0_OUT
• CPTS0_RFT_CLK
• I2C1_SCL
• CPTS0_HW1TSPUSH
• UART3_RXD
• SPI7_CS0
• GPIO0_58 

So, the closest thing that I think you are looking for is the datasheet I linked above, specifically "Table 6-1. Pin Attributes" section.
