Hello to everybody!
I'm new to NXP micro so sorry if the following questions are pretty basic.
Currently, I'm customizing my own board with LPC51U68 micro and I do have some questions regarding bootload through USB.
1- Is it possible to boot a binary firmware file to the flash using USB or should I use JTAG pins through an OM40005 board? I've seen the documentation regarding ISP modes (3.2 PIN description of LPC51U68 User manual) but I'm pretty confused.
2-If I need a developer board will I need mandatory an OM40005 or can I use an OM13058 for instance?
3-I've connected directly LPC51U68 USB pins to USB connector and when I reset the LPC51U68 my PC finds CRP DISABLD disk (see attached image) but when I replace the firmware.bin to another binary file and reset LPC51U68, it finds the same previous firmware.bin file (manufacturer firmware). What am I doing wrong?
Hope you can help me.
All the best,
