Description:
1, RL-USB source if necessary, it will DAPLink (CMSIS-DAP) which lead out to code for a USB, DAPLink to open the RL-USB Device code.
It can be reversed, based on a project template and then transplanted SWD interface related documents, to achieve a DAPLINK downloader.
2, compared to the old version of the new RL-USB features a lot of strong, such as the new WebUSB and better co-ordination WinUSB host computer development.
3, the new RL-FlashFS V6.X compared to the old version more powerful, more comprehensive API (FlahFS is used in the standard C library API), has supported When you delete a folder, delete the sync subfolders.
4, RL-FlashFS is compatible Fat, the new version supports a maximum capacity of 2TB. EFS also supports embedded file system, mainly for NOR-type Flash.
5, the new RL-FlashFS V6.X and the RL-USB NAND complete solution for everyone behind the production, support to the V7.
6, RL-FlashFS and FatFS difference:
(1) FatFS class is merely a FAT file system member, equalization erase bad block management, power-down protection, and the ECC check are not supported. These require users themselves to achieve, and FlashFS support.
(2) RL-FlahFS operation file name, does not support Chinese, and FatFS support.
