Secondary bootloader examples

[wouterdhondt]

Hi

I'm looking for an example to create a secondary bootloader for the PN7462 (next to the default ROM USB bootloader). I have the regular application examples like the dooracces, HIF and poll examples. But can't find anything on creating a secondary bootloader. Any ideas or directions?

Hello,

Do you want to use PN7462AU UART and X-Modem for application update, in order to implement a secondary downloader?

In this case, you should refer to the  AN10995 - LPC1100 secondary bootloader (with software). The secondary Bootloader project described here is implemented with the M0 LPC and many concepts described could be reused also in PN7462AU secondary project.

Could you provide us with additional information on this request?

Regards,

Ivan.
