Programming On-Chip Flash Memories of 56F80x Devices Using the JTAG/OnCE In

forcreat — Sat, 02 Aug 2025 02:48:36 GMT

I am currently developing the NXP series MC56F827 series chips and want to program the on-chip FLASH of this chip through the JTAG interface. I found that the example code in the document "Programming On-Chip Flash Memories of 56F80x Devices Using the JTAG/OnCE Interface" only shows a part. I wonder if the official has detailed code examples or SDK packages.

Hello @forcreat ,

Thanks for your post.

The 56F82x is an old product that has been around for more than 20 years. For the document "Programming On-Chip Flash Memories of 56F80x Devices Using the JTAG/OnCE Interface", we do not have detailed code examples.

You may refer to On-Chip Flash Programming of Freescale's MC56F827xx via JTAG Interface, which includes the corresponding software AN4981SW.

Hope it can help you.

BRs,

Celeste

Thank you very much for your effective reply. I saw the corresponding macro definitions and function names in AN4981SW. Then, are the MC56F837XX and MC56F847XX series also suitable for this?

-> Yes, they use the same DSC56800AEX core. And you can also port the code to other platforms with any processor.

Hope it can help you. Any new issues, welcome to create new post.
