在VisionFive2上按官方的文档烧录edk2到QSPI flash失败了的原因？

按照官方给的VisionFive2的EDK2烧录文档把SPL和JH7110.fd烧到QSPI flash，SPL烧录成功，但是JH7110.fd烧录失败，日志如下：

sf - SPI flash sub-system
Usage:
sf probe [[bus:]cs] [hz] [mode] - init flash device on given SPI bus
and chip select
sf read addr offset|partition len       - read len' bytes starting at                                           offset’ or from start of mtd
partition'to memory at addr’
sf write addr offset|partition len      - write len' bytes from memory                                           at addr’ to flash at offset'                                           or to start of mtd partition’

or from start of mtd partition'                                          +len’ round up len' to block size sf update addr offset|partition len     - erase and write len’ bytes from memory

or to start of mtd `partition’
sf protect lock/unlock sector len       - protect/unprotect ‘len’ bytes starting
at address ‘sector’

请问这是为什么呢？烧录的文件也是官方下载的，文件大小也是正确的。
