Hi, I'm trying to communication with UART1 on OMAP-L138. At the moment, I can write message to the serial port but I cannot read some. I got the error 11: Resource temporarily unavailable.
To activate the UART1, I commented one line (see below) in board-da850-evm.c. I wonder what is "too much work in irq53", is it has anything to do with my problem? Is it a know bug to not be able to read from UART1 under Davinci? /* * shut down uart 0 and 1; they are not used on the board and * accessing them causes endless "too much work in irq53" messages * with arago fs */ *//__raw_writel(0, IO_ADDRESS(DA8XX_UART1_BASE) + 0x30);* __raw_writel(0, IO_ADDRESS(DA8XX_UART0_BASE) + 0x30); Thanks for support. Regards, Nicolas
