TMDS64EVM: Gpios in TMDS64 EVM

Raj Kumar
Intellectual 348 points
Part Number: TMDS64EVM

Hi TI,

I have a TMDS64 EVM Board,i run the hello_world_cpp example which is imported from the MCU+SDK and i want some clarity about below things,

1.what are the gpio's of a53 mpu,R5 Mcu & M4 Mcu.

2.How can we access those gpios ?

3.Is all the gpio's are exposed in my evaluation board(TMDS64EVM),if exposed can you mention specific port number like j1,j2 or something?

4.Can we able to implement the IPC(Inter Process Communication) between a53 mpu & R5Mcu core .

5.IPC between main domain and mcu domain is possible?

Thankyou!

    Hello Raj,

    I am going to assign your thread to a different team member who supports GPIO.

    Please create a separate thread for your IPC questions. I will help you on that new thread.

    Regards,

    Nick

    Hello Raj,

    Thanks for reaching out to Texas Instruments E2E support forum.

    There are three instances of GPIO modules. The GPIO pins are grouped into banks (16 pins per bank and 9 banks per module), which means that each GPIO module provides up to 144 dedicated general-purpose pins with input and output capabilities; thus, the general-purpose interface supports up to 432 (3 instances × (9 banks × 16 pins)) pins. Since MCU_GPIO0_[23:143], GPIO0_[87:143], and GPIO1_[88:143] are reserved in this device, general purpose interface supports up to 198 pins.

    The R5F and A53 cores are the part of Main domain and M4F core is part of MCU domain. Please see the below screenshot for details about GPIO accessible from specific domain.

    For more information about GPIO, please refer to section 12.1.2 General Purpose Interface of AM64x TRM.

    Please refer to AM64x Schematics for above details.
