MVR5510 OTP programming

We are currently testing the OTP programming of MVR5510AMDA0ES. I have entered the test mode, and MAIN_TM_STATUS=0X42, FS_STATE_REG=0XA001. Currently, the emulation is OK, and the OTP values read out are correct. However, once I power down the chip and then read the OTP values again, I find that the OTP is completely empty. How can I write to the OTP and complete the programming when the emulation is OK? Currently, VSUP1/2=12V, VDDOTP=8.5V, POWERON1=5V, POWERON2=3.3V
Note that I am using the I2C protocol to program the OTP, not the original factory tool. Could you please help me see what additional commands need to be executed to actually write to the OTP.

Thank you for your reply, although it is of no value to me. I need to solve a technical problem, but you gave me a sales proposal. I will discuss it with my boss.

我看了下你们是烧录器公司吗？假如是的话那么第三方想做我们烧录的合作伙伴是需要认证的您可以联系NXP的local的代表去商务谈判，所以我无法把烧写的程序直接给您。

good I'll ask our American colleagues to contact NXP, as they are responsible for the NDA with NXP. If necessary, I'll update you.

已经告诉你了 OTP不支持用自己的板子去烧写，因为里面有很多rule 要追寻这些都是保密的不对外开放，你要想自己做OTP 首选我们指定的板子去烧写，正常情况下你是无法正确读取OTP寄存器的值。能理解嘛?

我们不支持客户用自己的板子做OTP，大批量的时候可以选择第三方做OTP，小批量或者自己做OTP测试的话我建议您购买下面的板子：

SBC and PMIC Product OTP Programming Board | NXP Semiconductors

这两个组合还是比较有性价比。
