| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions.

* / fix erasing/protecting flashes with unspecified sizeSascha Hauer2016-04-191-1/+3
|/ | | | | | | | | | | | | | | | | fixes: 81737c1 mtd: Fix erasing of devices >4GiB Several places erased a complete flash partition passing ~0 as count to erase(). With the above commit count to erase was changed from an unsigned type to a signed type, so the (count > f->size - offset) check in erase() no longer triggers and the ~0 count is no longer adjusted to the whole device size. Among other things this results in saveenv failures on NOR flashes. This patch fixes this by introducing an explicit macro for erasing the whole device which is tested for in erase(). All other negative values are rejected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Giorgio <giorgio.nicole@arcor.de>

The regular console is designed for human input and is unsuitable for controlling barebox from scripts since characters can be lost on both ends, the data stream contains escape sequences and the prompt cannot be easily matched upon. This approach is based on the RATP protocol. RATP packages start with a binary 0x01 which does not occur in normal console data. Whenever a 0x01 character is detected in the console barebox goes into RATP mode. The RATP packets contain a simple structure with a command/respone type and data for that type. Currently defined types are: BB_RATP_TYPE_COMMAND (host->barebox): Execute a command in the shell BB_RATP_TYPE_COMMAND_RETURN (barebox->host) Sends return value of the command back to the host, also means barebox is ready for the next command BB_RATP_TYPE_CONSOLEMSG (barebox->host) Console message from barebox Planned but not yet implemented are: BB_RATP_TYPE_PING (host->barebox) BB_RATP_TYPE_PONG (barebox->host) For testing purposes BB_RATP_TYPE_GETENV (host->barebox) BB_RATP_TYPE_GETENV_RETURN (barebox->host) Get values of environment variables Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Tested-by: Andrey Smirnov <andrew.smirnov@gmail.com>
