• the width of AXI ID conflict
    Hi: I have an idea that A15 and R7 are located on different AXI buses to build two systems respectively. In order to be more flexible, I hope to connect the two systems so that they can access each...

    Hi All, I am using UART to receive values and then write those values to SRAM. I am using the Texas Instruments Stellaris LM4F120 board. For this purpose, I am using the memcpy() function to write the...
  • Dynamic memory allocation and UART
    Hi friends, I came across a problem with my UART communication.My codes are below. if I use rx_buffer = (uint8_t*)calloc(3,sizeof(uint8_t)); HAL_UART_Receive_IT(&huart1,&rx_data,1); and rx_buffer = (uint8_t...
  • AXI fixed burst to a slave with narrow data width
    Hi, I have an AXI master with data width 64, and an AHB slave of data width 32. What would happen when there is a 64bit FIXED burst READ (i.e., asize=3 )to an address 0X100 of the slave? Would the...
