udisk_bootloader

udisk firmware update bootloader for 3D printer

需要修改 framework-arduino-lpc176x/system/CMSIS/system/LPC1768.ld, 保留64K空间给bootloader

/* Reserve first 64K (16 sectors * 4KB) for bootloader
 * Reserve the last 32KB sector for EEPROM emulation
 */
/* FLASH (rx) : ORIGIN = 0, LENGTH = (512K - 96K) */
/* FLASH (rx) : ORIGIN = 64K, LENGTH = (512K - 96K) */
FLASH (rx) : ORIGIN = 0K, LENGTH = (512K - 96K)
RAM (rwx) : ORIGIN = 0x100000C8, LENGTH = (32K - 0xC8)

需要修改 framework-arduino-lpc176x/system/CMSIS/lib/usb_host/filesystems/fatfs/src/ffconf.h, 去掉长文件名支持。 #define FF_USE_LFN 0
