LPC54608 Bootloader

[jordanliu]

Do you have a bootloader sample for LPC54608 that it can check if there is a USB drive thumb which has a firmware.bin in side? If yes, it will copy the binary file to flash. If not, the board will boot from the flash. 

If you don't have sample for LPC54608? Do you have any recommendation or suggestion?

Thanks

Jordan

Hi Jordan Liu,

Thank you for your interest in NXP Semiconductor products and 

for the opportunity to serve you.

The ISP USB mode can provide the similar feature as you mentioned before, you can learn the more information in the 3.1 Loading applications using USB mass storage boot (MSC class) mode section of the UM11035 lpc54608 board's user's guide.

Have a great day,

TIC

Hi Jeremy,

Thanks for your reply. Yes, I saw the 3.1 loading applications using USB

mass storage boot. It enumerates the device into a file folder at the

computer. However, I want to copy the firmware from USB disk into flash. Do

you have any other suggestion.

Thanks

Jordan

Hi Jordan,

Thanks for your reply.

To implement this application, you can follow these steps.

1. Using the usb_host_msd_fatfs demo as the template demo, which is from the LPC54608's SDK: Welcome to MCUXpresso | MCUXpresso Config Tools 
2. You need to add some flash API to execute various function, for instance, erase, program flash.

Hope this helps.

Have a great day,

Hello,

Doesn't the usb_host_msd_fatfs demo using the USB libraries and drivers that are located within the application flash?

If so, don't we lose access to those usb library functions (and usb drivers) when we erase the flash in preparation for reprogramming the flash with the new firmware.bin?

I believe we need to use the usb library that is located in the rom.
