I have verified on official lpc54608 board, I also meet the same problem with my target LPC54606 board, after flash magic download the code, then do the verify.
I meet first block CRC error problem as attached picture, and go to the next step, the flash magic say the address 0x00000004 is different.
But I use the JLINK to read out the chip flash 0x00000004, and compare it with the .hex file, I find the data is totally the same.
So, I think it is may caused by the flash magic bug. Could you help check it?
