This release includes two partially completed +ports, several new features, and a couple of important bug fixes. The two partially +completed ports are: + + * The STMicro STR71x processor and configuration for the Olimex STR-P711 + board. + * The Hitachi SH-1 using the SH1_LCEVB1 (SH-1/US7032EVB1) board + +Progress on these ports is stalled (as detailed in the ChangeLog). + +The new features focus primarily on management of block devices and extensions of +the NuttShell (NSH). These include: + + * A loop device that converts a file into a block device. + * A block to character (BCH) driver that allow access a block device as + if it were character device. + * Added strcasecmp() and strncasecmp() libc functions. + * Added the 'dd' and 'losetup' commands to NSH. These commands (along + with mkfatfs and mount), give good managment of filesystems on the target. + +Several bugs were fixed, the most important of which are: + + * Fixd a race condition workaround delay in LPC214X SPI logic. This was also + the cause of some bad MMC/SD performance on that platform. + * Fixed a recently introduced FAT file system problem: It would mount a (invalid) + FAT file system even if the medium is not formatted! + * Corrected two iother important errors in the FAT lseek implementation: + (1) the sectors-per-cluster value was being reset to "1" and (2) important + lseek logic was omitted when the seek position was zero. + +The FAT filesystem has had many bugs fixed in it and, I think, is now maturing +and becoming stable. + +These changes were verified only on the mcu123.com NXP LPC2148 board, the Hitachi +SH1_LCEVB1 board, and the Linux simulator, all using a Linux development environment. +Please report any errors to me. + +This tarball contains a complete CVS snapshot from November 16, 2008. |
