C2000WARE: Infinite loop in library

Hi Eddie,

For the SCI_readCharArray() function, the recommended usage is to call this from a SCI RX ISR, in which case it won't be called unless the proper number of bytes are present in the RX FIFO (or in non-FIFO mode, at least one byte is present). This while loop is really only included for if users are doing a polling approach rather than an interrupt approach, which would not be recommended in time-critical systems.

With the SPI_writeDataBlockingFIFO() function, this should never get stuck in an infinite loop. The while loop will wait until there is at least one spot available in the SPI TX FIFO. Since data is continuously shifted out of the TX FIFO, it will always eventually break out of this loop. In most cases, it should immediately break out of the loop. If they wanted to ensure this loop is never entered, they can call this function from a SPI TX ISR, that way it will only be called when the correct amount of FIFO spots is available to be written.

For both of these cases, I don't believe there is a plan to change these while loops in the driverlib functions since it is important to block unwanted writes/reads to/from the FIFOs.

Best Regards,
