Hi Ti,

I want to implement uart data received interrupt handler with TI-RTOS and TivaWare driver lib .

Data received and send is working fine in register pull mode.

Using this two API of Tivaware driver lib.

But I want to received data in interrupt mode using Tivaware and TI-RTOS .

BUT when i use this API i get Flash memory not fit for memory full.

So , How to configure the TI-RTOS for UART received interrupt ???

Hello Sumit,

Please see the following FAQ on how to correctly add interrupts into TI-RTOS: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/849627/faq-can-i-update-the-vector-table-with-intregister-when-using-ti-rtos

The "ti.sysbios.family.arm.m3.Hwi: Vector Table must be placed at or below 0x3FFFFFC00" error occurs because the "Runtime Vector Table address" has been set to 0xe000ed08.

0xe000ed08 is the address of the NVIC Vector Table Offset (VTABLE) peripheral register .

The "Runtime Vector Table address" should be the address of the vector table in FLASH or SRAM. The TI-RTOS start-up code will write the start address of the Runtime Vector Table to the NVIC VTABLE register.

I.e. in TI-RTOS configuration try changing the value of "Runtime Vector Table Address" from 0xe000ed08 to 0x20000000 (start address of SRAM).

That is what was shown in the FAQ Ralph referenced.

Hi Ralph,

As per your suggestion we change the vector table value we get lots of error .

Now Chester has said this (given below), so please go though the communication thread.

Hi Chester ,

How to received the uart data in interrupt mode?? I am using TI-RTOS and TivaWare driver lib. So how to configure the TI-RTOS for communication

Interrupt or Hardware interrupt?? Please help us on this issue . This is our main problem.

Regards,

Sumit Chaulya.

Between the FAQ I shared and Chester's detailed explanation of the error, I am not sure what else to really provide you here.

I would recommend reading the SYS/BIOS User's Guide, especially chapter 3.4 Hardware Interrupts: https://www.ti.com/lit/ug/spruex3v/spruex3v.pdf#page=58

We also have a getting started guide that you can reference along with the FAQ: https://www.ti.com/lit/pdf/SPRUHU5

Lastly see if you can also leverage existing TI-RTOS examples provided through TI Resource Explorer.
