Flashmagic does not program

[MVWare]

Hi, I developed a board with the NXP LPC55S69. I have already developed a program with the Xpresso IDE.
My applications runs fine with the Segger Jlink on the SWD port.

I added the USB connection on USB1 of the device in the design.
I installed latest Flashmagic: 13.50 build 6367, it has USB driver 3.02 on windows 10

I enable the ISP with a jumper. Connect the USB ; from PC to my board. (Which also powers my PCB)
I folowed the setup of flashmagic: select USB LPC55S69. A hex file.
Device LPC55S69 (USB, LPC5500)
Interface tiegf6JWnvo5 (USB Bootloader)
   reading Signatures works.
   reading sectors works
   erasing sectors works.
But programming works not: (pressing START)
LPC55S69(USB, LPC5500) Operation Failed. (programming - failed to send data to the device)

In the Preferences:
hardware tab shows the UART selection bullets (as if the programmer will use UART? )
other tabs are default.

What is going wrong here? or do I do somthing wrong?
I enables debug mode, but can not find the debug file.

Hi,  Thanks.  It was some time ago this ticket.
As I remember, the question was about ISP over the USB port, that is not working,
Over UART is works.
Or has it been fixed in the mean time?

Hello @MVWare,

I came to this thread because I had a similar issue.  I ended up solving my problem for an LPC802 by the way I generated the .hex file.  I noticed in the tool that the .hex file was much larger than the allowed memory, so I changed my build configuration from <debug> to <release> in MCUXpresso.  Now my .hex file only uses 50% of the memory and programmed succesfully.

Best Regards,

Dmitri

Hi Dimitri,  thanks for your reply.  This case is old for me.  We did not proceed the problem.
If I ever get beack to this issue, i will remember you hint.  thx!

Hello @MVWare,

Could you please take a look to the following information?

• LPC55S69: USB1 not detected when in ISP - NXP Community
• How to use LPC55S28 Bootloader - NXP Community

Also, may be useful to try the following recommendations:

• Use another .hex file
• Just for double check, please check if your USB1 port is working (e.g. testing an example)
• Try the method explain here for ISP mode: Flash Magic Programing LPC - NXP Community

Let us know if any of this helps you.

Best regards, Raul.

Hi Paul,

Interface tiegf6JWnvo5 (USB Bootloader)
   reading Signatures works.
   reading sectors works
   erasing sectors works.

So I woulkd like to conclude that the ISP interface is communicating.  right?
Afterthis, programmig does not work...

Is flashmagic still alive? That forum is quite dead.

next update:
So On my board with LPC55S69 the flashmagic ISP works on UART.
It does not work on USB1,  although signature, read and erase works fine.
On the 55S69 NXP Eval board:  exactly the same behaviour!

On USB the flashmagic crashes very often. just exit at once.

Is flashmagic supported somewhere?  by NXP?  The site it's self does not reactot any forum question.
BLHost seems not very practical.

In the mean time:   ISP with flashmagic on the UART port works.

Hello @MVWare,

As you mention, ISP communication is working, but FlashMagic is failing at programming. This issue should be reviewed by FlashMagic team, please try to contact them through this way: Contact Support - Flash Magic, since you do not have success in the Forum.

As a recommendation, you could try and use our MCU Secure Provisioning Tool, we test the LPC55S69 EVK for uploading a binary trough USB1 and works.

Best regards, Raul.

Hi Raul,  thanks for helping.
Does this MCU SPT work on  the ISP of the LPC55?
I don't read any thing about ISP in this tool...
in the mean time i'm still waiting for flashmagic support aswell...

[RaRo]

Hello @MVWare,

Yes, MCU SPT work on ISP for the LPC55xx. The compatible devices list is at the following link: MCUXpresso Secure Provisioning Tool | NXP Semiconductors.

[MCUXpresso Security Provisioning Tool List of Supported Devices]

Also, there you may find the MCUXpresso Security Provisioning Tool User Manual, which might come in handy if you decide to use the tool: MCUXpresso Secure Provisioning Tool User Guide v.5. In here it mentions the possibility and use of ISP in the supported devices.

[MCUXpresso Security Provisioning Tool User Manual. Section 6.1.5. Connection]
