can anyone help me with UART - DMA Tx on Freescale MPC5744P. Im using Micrium uCOSIII Operating system, and DMA_Tx_Init is in one of the tasks (before while loop).
When i'm using DMA for UART Tx without OS it works great, but when uCOS is involved, DMA isn't triggering.
I suppose there are some flaws in my code involving interrupts, but i can't find any bugs.
Are there any known issues with uCOSIII involving DMA and/or interrupts?
Also, i'm not sure, if there are any special interrupt or int_vector i should enable or set?
