Kinetis K70: Bootloader with USB?

arnogir — Wed, 21 Jan 2015 14:38:24 GMT

Hello every body.

I'm looking for a Bootloader which allow to get a program (In S19 or other type file) from the USB (i.e an USB KEY) and then flash into internal flash.

I see this link,

Kinetis Bootloader|Freescale

But it seem not work for K70.

Is existing a sample?

Thank

Hello Arno Gir:

The document in the next link by colleague Adrian Sanchez might be what you are looking for:

TWR-K70 MSD HOST Bootloader based on AN4368 source code

Hi every body.

I taken code from

TWR-K70 MSD HOST Bootloader based on AN4368 source code

It work fine. I just need to do some correction because the Boot was Max address for a K60 (512K) no for a K70 (1M)

Then I modified following:

#define MAX_FLASH_ADDRESS 0x0007FFFF

#define MAX_FLASH_ADDRESS 0x000FFFFF

and in main.c

uint_8 erase_flash(void)
{ 
    /* Body */
    uint_8 error = FALSE;
    uint_8 i;
[...]

uint_8 erase_flash(void)
{ 
    /* Body */
    uint_8 error = FALSE;
    uint_16 I;

Many thank.

Is existing an "Add-on" to this bootlaoder to Get file on an external NandFlash (NFC) instead of USB?

Hi,

In waiting answer for the possible Add-on to use NandFlash, I discovers a problem with the current boot.

When I flash with P&E and start with It, bootloader start. But in standalone, nothing start.

I use the Flash build option (Not RAM).

Do you have an Idea?

Hello Arno Gir:

Unfortunately there is not an addition to implement bootloader with a NandFlash, sorry.

As for the issue, maybe it is the project library configuration, check the next thread for the solution:

Re: MK10DX256VLK7 doesn't run standalone, just when debugging. Verified it's running from FLASH, not RAM.

The uTasker project includes support to load firmware from NAND flash.

However NAND is not a removable source such as a memory stick so there also needs to be a method of copying the firmware there before loading to application space. The uTasker project uses Ethernet web serve as standard loading technique to NAND on the board.

Generally however I don't see the relationship between the two loading techniques.

I will read this topic for the Load problem.

For the NandFlash, in fact my need is to copy:

USB\image.s19 -> Internal flash

USB\resource.pbr (PEG resource file) -> External NandFlash.

This is why I asked I exist a standalone Nandflash drivers which work without MQX? (Or a simpliest extract of MQX which use Nandflash drivers?)

Thank

Edit:

Thank! For the standalone problem! Project librarian option was on "ewl". I set it to "ewl_noio" and all work correctly!

:smileyhappy:

Still Nandflash simple driver problem:smileyblush:
