cant write more than 512 bytes to hyperflash on rt1062

[fischer_larry]

Im working with a custom board that is modeled around the rt1062 eval. We have a S26KS512SDPBHI02 1.8V hyperflash chip.  Ive been trying to program this flash chip, and Im having a problem.  Im able to program up to 0x200 bytes at a time.  After that, I see garbage, and I get an error.  Im using a combination of NXP-MCUBootUtility in master mode, and blhost from the command line.  I get the flashloader running on the target, and can talk to it directly via blhost.  I can erase all of flash, no problem.  

Here, I was writing a small amount of memory - foo.dat contained less than 0x200 characters and succeeded.  The contents is: "The quick brown fox jumped over the lazy sleeping dog."

C:\trash>C:\nxp\NXP-MCUBootUtility-master\tools\blhost2_3\win\blhost -t 5242000 -u 0x15A2,0x0073 -j -- write-memory 0x60001000 c:\trash\foo.dat
{
   "command" : "write-memory",
   "response" : [],
   "status" : {
      "description" : "0 (0x0) Success.",
      "value" : 0
   }
}

Here I was writing a larger amount.   Same contents repeated.  I had erased all of memory prior to this attempt.     

C:\trash>C:\nxp\NXP-MCUBootUtility-master\tools\blhost2_3\win\blhost -t 5242000 -u 0x15A2,0x0073 -j -- write-memory 0x60001000 c:\trash\foo.dat
{
   "command" : "write-memory",
   "response" : [],
   "status" : {
      "description" : "7000 (0x1B58) Unknown error code (7000)",
      "value" : 7000
   }
}

Its not a question of location - I can walk my writes up thru flash, as long as I keep them to 0x200 bytes or less.    I bet there is a simple explanation for this.

[fischer_larry]

Well, I finally made a bit of progress on this.  

I found a post on hyperflash and the eval boards that mentions that in addition to using the
1050 eval hyperflash driver on the 1062 eval board,
one needs to change the contents of the evkmimxrt1060_flexspi_nor_config.c file. 
I tried this on the eval board and our target hardware but wasnt able to make things work. 
However, it got me to thinking.  I tried running the flash tool from mcuxpresso and used the
1050_connect script on the target hardware.  I was able to successfully program the flash on
our target board.  I have confirmed that the contents are correct.  I cant program directly from
MCUXpresso, nor can I debug from there, but I can burn the flash.  After doing so, I switched
programmers to a JLink, and used NXP MCUBoot Utility to connect to the rom, which presumably
sets the correct registers for accessing hyperflash.  I then set the PC and stack pointers by hand from
JLink commander, and was able to run my program from flash. 

So clearly, the flash is working. 
There is one standard tool - flashburner - that knows how to program flash correctly.
I can execute from flash if I set things up manually.

The next questions are: Why cant MCUXpresso burn the flash directly?
Probably the same answer to - How can I debug from MCUXpresso?
And the follow-on question is probably answered in an appnote - how to set up my target
system/image so that it boots from hyperflash?  I dont have acces to the boot config GPIO
pins - the only thing I can do is burn fuses.

Thoughts on any of this data?

Hi,
Thanks for your reply.
According to your description, we can get that the issue seems to be nothing related to hardware.
As you mentioned above, it should adapt the evkmimxrt1060_flexspi_nor_config.c file to fit for hyperflash, in addition, it also needs to select the MIMXRT1060_SFDP_HYPERFLASH.cfx (as the below figure shows) when using MCUXpresso IDE to debug.

Have a great day,
TIC

I am in the process of doing the same thing.  If it works, then I know we have a HW challenge.  If it doesnt, then the flashloader image I have has some quirk.  I will let you know.  Thanks for chasing.

Larry

[fischer_larry]

And one last question - where did you get your flashloader image file?  That is the program doing all of the work here.  Do they have version numbers?  I want to use the same image as you are using.

Thanks,

larry

[jeremyzhou]

Hi,
Thanks for your reply.
1) Where did you get your flashloader image file?
-- The flashloader image resides in the NXP-MCUBootUtility directory, for instance, \NXP-MCUBootUtility-xxx\src\targets\MIMXRT1062\ivt_flashloader.bin.
Note: the version of NXP-MCUBootUtility is 2.3.0.

I changed the file to a predictable binary pattern.  You can see the corruption starting at 0x200

Hi,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
According to your reply, it seems that foo.dat should be less or equal to 0x200 (512) bytes then be able to be programmed to the Hyperflash， otherwise, it will encounter the write fail.
In further, you find that the content seems to be corrupted start from the 0x200 in the foo.dat.
Is my understand right?
If yes, I was wondering if you can share the schematic of connecting the HyperFlash, meanwhile, demonstrates the steps of programming in detail.
Looking forward to your reply.

Have a great day,
TIC

Hi Jeremy,

Thank you for responding.  Just to clarify, I am able to write to flash as long as the size is less than or equal to 512 bytes.  Anything beyond that gets corrupted.  This seems to be an issue with the flashloader that I download  to the target system.  

I have written a PC application that writes in blocks of 512 bytes, and it works perfectly.  I dont have a problem writing to any part of flash - its just that if I try to write a chunk that is greater than 512, it fails.  So if I ask blhost to write a file that has more than 512, it fails.

I will ask my client if I can share the schematic.

Thank you,
Larry

Here are the hyperflash connections for this board 

 

[jeremyzhou]

Hi,

Thanks for your reply.
After having a brief review of the attached schematic, I think it's right.
So I was wondering if you can demonstrate the steps of programming in detail, and in the custom board, whether the S26KS512SDPBHI02 would work as the boot-up flash device which likes the QSPI in the MIMXRT1060-EVK board.
Looking forward to your reply.
Have a great day,
TIC

Jeremy,

The issue seems to be with the flashloader image (ivt_flashloader.bin) that I download to the target board.  It is able to write only one page (512 bytes) of memory. The following log is from NXP MCUBootUtility.  If you are familiar with that utility, you can see me going thru the various stages:

 - connect to bootrom

 - Connect to flashloader (which downloads the flashloader)

 - Configure Boot device

 - Load bootable image

At the bottom, as I try to write the image, it fails.

Hi,

Thanks for your reply.
I change the MIMXRT1060 to enable the onboard Hyperflash feature and Hyperflash connecting is as same as your board, then I try to replicate your phenomenon on my site.
However, it works well actually, the attachment is log file.
Hope this is clear.
Have a great day,
TIC

Actually, Im waiting on a HW guy to ID the exact resistors.  I dont have a layout file that I can read and the labels on the board are not exactly obvious to me.  Can you point me to a picture that shows which are the resistors to change?
