LPC55S69 : errata "ROM bootloader updated to provide API functionality for entry to ISP mode"

Hi !

I latest errata for LPC55S69 I can see :

5.1 ROM bootloader updated to provide API functionality for entry to ISP
mode
ISP.1: Devices with date code 2101 (yyww) and ROM patch version (T1.1.5), the ROM
bootloader will be updated to provide an API (runBootloader API) for the user application
to enter the ISP mode based on the designated ISP interface mode.

So basically this kind of ROM is only possible to have at beginning of the next year .

Regards,

Eugene

Hi @EugeneHiihtaja

I just received confirmation from our applications team.

If you buy a part from Jan 2021 (and beyond) with the Rom patch versionT 1.1.5.

The run bootloader API (to invoke the bootloader from application code) will be available.

Diego.

Hi Eugene,

Currently, I do not have further information regarding any other changes. However, if they are aimed to solve any issue, they probably will be mentioned in the errata sheet.

Diego
