The current Y-Modem implementation has some limitations: - Y-Modem/G protocol is not supported - Multiple files (aka. batch) transfers are not supported - Transfer speed over fast lines (USB console) is slow - Code is not trivial to maintain (personnal opinion) This implementation tries to address all these points by introducing loady2 command. The effects are : - transfer speed for Y-Modem over USB jumps from 2kBytes/s to 180kBytes/s - transfer speed for Y-Modem/G jumps to 200kBytes/s - multiple file transfers are possible This command was tested on a USB console and UART 9600bps serial line : - NAKs (and retransmissions) were tested for faulty serial lines - multiple file transfers were tested - Y-Modem, Y-Modem/G and X-Modem transfers were tested Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Tested-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
