不知道你说的是哪种eFuse。

建议参考Zynq-7000的secure boot文档:

https://www.xilinx.com/support/documentation/application_notes/xapp1175_zynq_secure_boot.pdf

里面有不少例子,希望对你有用

Best Regards,
Jason

ARM可以通过Xilskey这个库的driver去烧写PS和PL的eFuse,可以参考Jason所说的这个文档。

但你需要注意,通过PS去烧写PL的efuse时,你需要通过MIO外部连接到JTAG口。

XAPP1075“The Secure Key Driver can program the PS and/or PL eFUSEs. To program the PL eFUSEs, four MIO outputs must be routed out of the MIO outputs into the JTAG pins. These are external connections which must be made on the printed circuit board.”
