S32R45: How to Modify the eFuse?

CSBoy — Fri, 30 Jan 2026 09:24:43 GMT

想了解一下s32r45如何对ocotp模块里的fuse进行编程？我们的板子想切换到boot from fuse模式。需要对ocotp模块里的boot_cfg1-3修改其配置。有什么工具能进行修改吗？

我尝试使用uboot里面的fuse工具，当不成功，显示如下：

一直卡在这个地方。

是否有文档工具介绍如何转量产？

Hello,

There is no public fuse programming tool for S32R45 up to my knowledge.

Since your company has direct NXP FAE it will be fastest to reach him out and ask for the programming tool.

I have also asked RADAR team for process here. I will update you once they reply.

Best regards,

Peter

Hello,

Usually fuses are programmed by SW. the OCOTP chapter in RM describes the procedure.

We can share Lauterbach programming example script with customers, but not via public community.

Since you have direct NXP support, please get in touch with him and he will guide you trough the process.

Best regards,

Peter
