Use FlashMagic programming LPC54608 RAM

[JennieZhjun]

Dear support,
We Use FlashMagic programming LPC54608 RAM in ISP Uart mode.
Now FlashMagic can read signature without issue.
Then I want to burn LPC54018 SDK flashloader bin file to target RAM (start from 0x2000000)through ISP uart. But failed. see attachment
Could you please advice where is the problem?

Thanks,
Jennie
