i.MX-RT1020 Debug Console

[yoshiyukiokada]

Hi support community,

I tried a  flexspi_nor_polling_transfer project with IMXRT-1020EVK.

The Debug console function works properly when it was under debug (connected with IDE).

However, it doesn't work when downloading a firmware into a Quad SPI flash. (not connected with IDE)  

I tried another sample project, e.g, lpspi_interruptb2b_master, the Debug console function works properly in both case.

I also tried a same project with IMXRT-1060EVK, the debug console function works properly in both case. 

Please tell me how the Debug console function works properly with IMXRT-1020EVK.

I use IDE and SDK as below;

IDE: MCUXpresso IDE v11.0.0

SDK IMXRT1020 SDK 2.6.1

Best regards,

Yoshi

Hi Yoshiyuki Okada,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
I'm not very clear with your issue, whether it's the flexspi_nor_polling_transfer demo project wouldn't run under non-debug mode.

Have a great day,
TIC

Hi Jeremy,

Thank you for your help. 

Unfortunately, I'm not sure how to confirm the flexspi_nor_polling_transfer demo project run or not under non-debug mode.

What I did was just build the project and flash it. Why the demo project doesn't work properly?

I would appreciate if you could try to reproduce it on your site.

Best regards,

Yoshi

Hi Yoshiyuki Okada,

Thanks for your reply.
After investigating, I find that the issue is caused by erase the sector which is also occupied by the flexspi_nor_polling_transfer itself.
So please change the EXAMPLE_SECTOR just likes below, and give a try again.
#define EXAMPLE_SECTOR 20

Have a great day,

Hi Jeremy,

I confirmed the sample project works properly with corrected source.

Thank you for your powerful support.

Could you please explain why the project with "original source" seems to work properly under debug-mode?

Best regards,

Yoshi

Hi Yoshiyuki Okada,

Thanks for your reply.

In the original source, it will erase sector 0, however, the sector is also occupied by the flexspi_nor_polling_transfer itself, it's the root cause.
Hope this is clear.

Have a great day,

Thanks for your help.

I understood the root cause of this issue, however, my question was why "original source" seems to work properly under debug-mode not but under non-debug mode.

Here, "debug mode" means that the EVK is connected with PC and IDE runs the program.

On the other hand, "Non debug mode" means that the program is flashed into Q-Flash on the EVK and RT1020 was boot from the Q-Flash.

Are there any difference between Non-debug mode and debug mode?

Best regards,

Yoshi

Hi Yoshiyuki Okada,

Thanks for your reply.

I've done the testing of debugging the lexspi_nor_polling_transfer project with IMXRT-1020EVK, it can run only once and it won't be available when clicking the Restart icon.
According to this phenomenon, we can't say it can work property under debug mode actually.

Have a great day,
TIC
