Re: [U-Boot] Unable to Receive 1Kb of data
Hi Sir, Thanks for the reply. I am trying to read around 1Kbyte of data from the serial port uart2. Standard serial console is uart1. I am using the function* NS16550_init() in drivers/serial/ns16550.c* file for the console initialization or configuration. I am using functions* NS16550_putc() *for sending data byte by byte and * NS16550_getc()* for receiving data(same file). By receiving and sending i mean to say the UART2 RX(receive) and UART2 TX(transmit) respectively. I have a device connected to serial port UART2 which sends the data around 1Kb. I am able to receive only 64 bytes now. This may be because of the FIFO limitation in H/W, which is 64bytes.
