Forum Post: RE: TM4C129ENCPDT: Project was working, and now I keep jumping to abort when BIOS starts

Hi Noah, [quote userid="589411" url="~/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1483128/tm4c129encpdt-project-was-working-and-now-i-keep-jumping-to-abort-when-bios-starts"]This project is based off of the tcpEcho project, and all other tasks except for those related to this initial example have been commented out.[/quote] Are you saying that you have stripped off everything that only the initial example which is the tcpecho code remains? Or you still have the UART RX and UART TX tasks running? What is actually running? If you download the tcpecho example again, I don't think you will see any abort issue right?

Any help is appreciated. Thank you! [/quote] In ROV, can you look under task and find out if there is a stack overflow? Can you use these two posts to debug the exception? How do I trace backward to the code that caused an exception in my TI-RTOS app? Debugging Common Application Issues with TI-RTOS
