Dear support,
I am using RT1170-EVK to getting familiar with RT117x MCU. According to chapter 10 of the `RT1170 Processor Reference Manual`, there is a "ROM bootloader" inside each RT117x chip and it supports so called "Serial download mode" which can be used to download programs to external flash devices.
Now I am having quite a few questions:
Regards,

Hi @yf2 ,
Thanks for your reply.
1) Did you mean that the ROM bootloader supports "load-image" and "execute" commands to load and run the flashloader program and then we should follow the flashloader manual to use the flashloader program to do more jobs?
-- Yes, just like the link illustrates.
Have a great day,
TIC

Hi @yf2 ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1)Is this "ROM bootloader" same thing as the "MCU bootloader"?
-- Yes, they're similar.
2) Where I can find a list of supported property ids of this ROM bootloader?
-- I don't know, usually, we just use the ROM code to load the flashload which supports more available commands.
3) How they are related to this ROM bootloader? When I should use them?
-- No, the mcu-boot is as same as the flashloader demo except for it can work in the flash.
Have a great day,
TIC

only app image(flashloader) with ivt header can be supported by BootROM 'load-image' command, and it will jump to app directly after issuing load-image command, so you don't need to issue 'execute' command any more.
Yes, you cannot do flash erase/write work by BootROM commands, so we have to do it in 2nd flashloader.
