RT1064 Flashloader and Internal ROM and Flash.

emvlabs — Sat, 14 Dec 2019 15:44:05 GMT

I am developing RT1064 using IAR.

Please check below, Is it possible or not.

1. Flashloader into Internal using JLINK.

2. My App into internal flash using flashloader.

3. My App using Internal Flash and internal ROM.

Boot sequence are below

1. Power on

2. Flashloader on the internal ROM

3. 1 seconds timeout then jump to My App from Internal flash.

Question

1. I can't find the IAR linker file which use internal flash(4MB) and internal RAM(1MB).

2. I found the flashloader example. Is it possible download to internal ROM(128KB).

3. Is it possible boot from internal ROM.

4. if possible boot from internal ROM, then jump to internal flash. is it possible ?

Hi ChoonGyeong Lee ,

Internal ROM is fixed, you can't modify it.

The flashloader normally can download to the internal RAM, then run it under the serial download mode.

But if you are using the IAR, you can debug it directly, the IAR and the JLINK will call the related flashloader code for RT1064. Then you can debug your app directly, you don't need to consider the flashloader.

Now, answer you questions:

1. I can't find the IAR linker file which use internal flash(4MB) and internal RAM(1MB).

Answer: You can refer to the SDK project for RT1064:

SDK can be downloaded from this link:

Welcome | MCUXpresso SDK Builder

2. I found the flashloader example. Is it possible download to internal ROM(128KB).

Answer: Just as I said, ROM is fixed, it is not used by the customer.

3. Is it possible boot from internal ROM.

Answer: Please check the boot mode:

4. if possible boot from internal ROM, then jump to internal flash. is it possible ?

Answer: In factor, when you boot, the ROM code will run automatically, you don't need to control it.

You just need to download the code to the internal flash, then set the boot mode as internal boot, then the ROM will help you to boot the app from internal flash with ROM boot function automatically.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Thanks for your kind explain.

But I have some questions yet.

1. flexspi_nor.icf is used the external SRAM, so I try to internal RAM is it possible ?

2. Boot Mode 00 works with MfgTool. is it right ?

- Set boot mode 00 or 01 ?

- Power on the target.

- MfgTool Start

- MfgTool download app to internal flash.

Thanks

Hi ChoonGyeong Lee,

1.flexspi_nor.icf is used the external SRAM, so I try to internal RAM is it possible ?

Answer: If you read our SDK document Getting Started with MCUXpresso SDK for MIMXRT1064.pdf carefully in SDK_2.6.1_EVK-MIMXRT1064\docs, you will find it is not the problem.

• Debug – Compiler optimization is set to low, and debug information is generated for the executable. The linker
file is RAM linker, where text and data section is put in internal TCM.

Boot Mode 00 works with MfgTool. is it right ?

- Set boot mode 00 or 01 ?

- Power on the target.

- MfgTool Start

- MfgTool download app to internal flash.

Answer: boot mode 00 is using the fuse to boot it. Please check the RT1064 system boot chapter 8, you will find the mode0 and mode 1 difference.

When in boot mode 00, If BT_FUSE_SEL = 0, indicating that the boot device (for example, flash, SD/
MMC) was not programmed yet, the boot flow jumps directly to the Serial Downloader.

So, it will enter the serial downloader mode, you can use the mfgtool to download the app through the UART or the HID.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Dear Kerry,

Please check the sequence.

1. I use the iled_blinky project.

Hi ChoonGyeong Lee,

Do you want to download the code to the board, and you meet the problems, right?

Now, two ways for you to download the code, just take SDK iled_blinky project as an example.

1. generate the app.srec file

After you build the project, you will find the rt1064_iled_blinky.srec under folder:

SDK_2.6.1_EVK-MIMXRT1064\boards\evkmimxrt1064\demo_apps\led_blinky\iar\flexspi_nor_debug

2. Use MCUBootUtility to download the app code

https://github.com/JayHeng/NXP-MCUBootUtility/archive/v2.2.0.zip

the related user manual is:
https://github.com/JayHeng/NXP-MCUBootUtility

You can let your board enter the serial download mode, then use the mcubootutility tool to download the code.

3. MFGtool download

You can refer to this application note, generate the .sb file to download it.

Please refer to application note: AN12108.

https://www.nxp.com/docs/en/application-note/AN12108.pdf

It has the detail steps.

In my own opinion, MCUbootutility is more easy to use.

Please try it again.

If you still have questions, please kindly let me know.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,

emvlabs — Wed, 29 Jan 2020 14:54:53 GMT

Dear Kerry,

Please check the build option

DEBUG

XIP_EXTERNAL_FLASH=1

XIP_BOOT_HEADER_ENABLE=0

XIP_BOOT_HEADER_DCD_ENABLE=0

CPU_MIMXRT1064DVL6A

Is it right ?

Also please check the option.

I download success, but it do not work.

I move the 7-3 switch ON.

Then reset

but no response.

What is wrong ?

kerryzhou — Sat, 01 Feb 2020 14:57:56 GMT

Hi ChoonGyeong Lee,

Thanks for your updated information.

Do you try to use the offiical SDK code, for example, the very easy project, led blinky, then generate the firmware and use the MCUBootUtility tool to download it?

Another way, you can try the MCUbootUtility tool app firmware to test it at first:

\NXP-MCUBootUtility-2.2.0\apps\NXP_MIMXRT1064-EVK_Rev.A

Please try it again.

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Hi Kerry,

It works,

I found that I didn't push the [All in-one Action] button before.

Now, It runs on internal flash. Is it right?

Thanks for your kind supports.

Re: RT1064 Flashloader and Internal ROM and Flash.

kerryzhou — Wed, 05 Feb 2020 08:31:09 GMT

Hi ChoonGyeong Lee,

Push the All in-one Action will download the APP code to the MIMXRT1064 internal Flash( in factor just put one QSPI to the chip internal side, still use the flexSPI to communicate with the QSPI flash).

After you download it, then set the chip mode to the internal boot , then your internal flash code will run.

Wish it helps you!

If you still have questions about it, please kindly let me know.

Have a great day,
Kerry

Hi Kerry,

I try to use the your demo project.

But some functions are exist in the "fsl_clock.c"

My project is base on the littlevgl_demo.

be_api.c functions are already implemented in the "fsl_clock.c".

I think that I must use the be_api.c functions instead of "fsl_clock.c"

Is it right ?

I'm really thanks for your help.

Hi ChoonGyeong Lee,

My demo project? Do you try the simple project, iled_blinky? Is it works?

If you are using littlevgl_demo, which SDK version you are using now?

So, you means I must use the rt1060_rom_api base on SDK2.7.0.

Is it right ?

Thanks

Re: RT1064 Flashloader and Internal ROM and Flash.

kerryzhou — Wed, 26 Feb 2020 12:22:20 GMT

Hi ChoonGyeong Lee,

I am a little lost in your new question, do you mean you use the littlevgl_demo, and can't download it?

Please give me more details.

Please use the newest SDK, BTW, please check your code, whether you are using the SDRAM or not, if you are using the SDRAM, you also need to add the DCD configuration in the MCUBootUtility tools.

Have a great day,
Kerry

Hello

Quad-SPI Flash in i.MX 1064.

Getting the flashloader working on the MIMXRT1064-EVK will be an amazing hurdle to get over. This flashloader was ported over from that of a different MIMX family member, the 1050. I know that the 1064 has 4MB of Quad-SPI Flash. This shows up as external memory in section 2.1 of "i.MX RT1064 Crossover Processors Data Sheet for Consumer Products, Rev. 0.1 01/2019" and appears on the block diagram as "Dual Channel QuadSPI" "Hyper Flash." On the same block diagram, we show an Internal memory of 4 MB Flash. Can anyone explain if this flash exists as shown on the diagram, and/or if it actually somehow the same flash as the QuadSPI external memory.

More specifically, in my evkmimxrt1064_flashloader Eclipse project, I currently have the following #define found in bootloader_config.h

// Internal Flash features
#define BL_FEATURE_HAS_NO_INTERNAL_FLASH (1)

I believe this is this correct for MIMXRT1064, as QSPI is external to the CPU bus. If I try making this a (0) zero, it tries to #include <fsl_flash.h> which I don't have in my SDK, and so cannot build.

Any suggestions are welcome.

Cheers.
