FRDM-K82 QSPI XIP problem

hemlock — Mon, 21 May 2018 20:39:23 GMT

Hello. I am trying to load the 'led_demo_qspi_0000' project from: <NXP_Kinetis_Bootloader_2_0_0>/apps/demo_qspi/led_demo/targets/FRDM-K82F/kds/led_demo_qspi_0000
loaded onto the QSPI on the FRDM-K82 board and am running into the following issue:

1) I can write the QSPI config:

blhost.exe -p COM5 -- write-memory 0x20000000 qcb_MX25U3235F_parallel_mode.bin
...
Response status = 0 (0x0) Success.
blhost.exe -p COM5 -- configure-quadspi 1 0x20000000
...
Response status = 0 (0x0) Success.
blhost.exe -p COM5 -- write-memory 0x68000000 qcb_MX25U3235F_parallel_mode.bin
...
Response status = 0 (0x0) Success.

2) I can write an SB file, by using the board file 'qspi_image_0000.bd':

# The sources block assigns file names to identifiers sources
{ # SREC File path
mySrecFile = "led_demo_qspi_0000.srec";
# QCB file path
qspiConfigBlock = "qcb_MX25U3235F_parallel_mode.bin";
}
# The section block specifies the sequence of boot commands to be written to
# the SB file
section (0)
{
#1. Erase the vector table and flash config field.
erase 0..0x800;
# Step 2 and Step 3 are optional if the QuadSPI is configured at startup.
#2. Load the QCB to RAM
load qspiConfigBlock > 0x20000000;
#3. Configure QuadSPI with the QCB above
enable qspi 0x20000000;
#4. Erase the QuadSPI memory region before programming.
erase 0x68000000..0x68004000;
#5.Load the QCB above to the start address of QuadSPI memory
load qspiConfigBlock > 0x68000000;
#6,7. Load all the RO data from srec file, including vector table, flash config field and codes.
load mySrecFile;
#8. Reset target.
reset;
}

and using the command :

./elftosb.exe -V -c qspi_image_0000.bd -o qspi_image_0000.sb

3) But when I try and write the sb file using blhost I get an error:

blhost.exe -p COM5 -- receive-sb-file qspi_image_0000.sb
Ping responded in 1 attempt(s)
Inject command 'receive-sb-file'
Preparing to send 3904 (0xf40) bytes to the target.
Successful generic response to command 'receive-sb-file'
Data phase write aborted by status 0x2712 kStatus_AbortDataPhase
Response status = 10200 (0x27d8) kStatusMemoryRangeInvalid
Wrote 128 of 3904 bytes.

Additionally -- if I try and go through the steps in the sb file manually:

blhost.exe -p COM5 -- flash-erase-region 0x000 2048
Ping responded in 1 attempt(s)
Inject command 'flash-erase-region'
Response status = 10200 (0x27d8) kStatusMemoryRangeInvalid

So I suspect that the initial step in the SB file 'erase 0 ... 0x800' is failing.

Is there a write protect step I should be disabling? I don't think that I have a key for this image:

blhost -p COM5 -- read-memory 0x400 12
Ping responded in 1 attempt(s)
Inject command 'read-memory'
Successful response to command 'read-memory'
ff ff ff ff ff ff ff ff ff ff ff ff
Successful generic response to command 'read-memory'
Response status = 0 (0x0) Success.
Response word 1 = 12 (0xc)
Read 12 of 12 bytes.

Find attached: the map and linker files for this project:
MK82FN256xxx15_qspi_0000.ld = linker file for led_demo_qspi_0000
led_demo_qspi_0000.map = map file for led_demo_qspi_0000
MK82FN256xxx15_application_0x0000.ld = linker for freedom k82 bootloader
freedom_bootloader.map = map file for freedom k82 bootloader

What I want is for the freedom bootloader to execute in flash, initialize the QSPI in parallel mode, then jump to 0x68001000 and start execution of the led_demo_qspi housed there.

Please let me know what I have done wrong.

Another data point is that I cannot write to the FOPT as the "Kinetis Bootloader QuadSPI User's Guide.pdf" suggests -- is this a security feature perhaps? Is there another user guide that describes how to enable QuadSPI for K82?

Hello John,

Please refer to "Kinetis Bootloader QuadSPI User's Guide.pdf" (path:NXP_Kinetis_Bootloader_2_0_0\doc) .

About the QCB file , you can directly use KBOOT provicde : NXP_Kinetis_Bootloader_2_0_0\apps\QCBGenerator\binaries\qspi_config_block.bin

About the .BD file , you can first use KBOOT provide :NXP_Kinetis_Bootloader_2_0_0\apps\demo_qspi\bdfile\qspi_image_0000.bd

I test with the usb port of FRDM-K82F board, it can work well .

Please refer to it have a try, if still have question , please contact us without any hesitate .

Hope it helps

Have a great day,
TIC

Howdy Alice,

I've re-run elftosb.exe -V -c qspi_image_0000.bd -o qspi_image_0000.sb against the files you mentioned to generate a new .sb file, however I'm still seeing a "kStatusMemoryRangeInvalid" error after 160 bytes on my FRDM-k82F board:

blhost -u -- receive-sb-file qspi_image_0000.sb
Inject command 'receive-sb-file'
Preparing to send 3904 (0xf40) bytes to the target.
Successful generic response to command 'receive-sb-file'
usb hid detected receiver data abort
Data phase write aborted by status 0x2712 kStatus_AbortDataPhase
Response status = 10200 (0x27d8) kStatusMemoryRangeInvalid
Wrote 160 of 3904 bytes.

Find attached, my led_demo_qspi_0000.srec file, which was from the project located at: NXP_Kinetis_Bootloader_2_0_0/apps/demo_qspi/led_demo/targets/FRDM-K82F/kds/led_demo_qspi_0000/release

To generate the .srec file, the following command was used:
arm-none-eabi-objcopy -v -O srec "${BuildArtifactFileName}" "${BuildArtifactFileBaseName}.srec"

Hello John,

I use the .srec file you shared , it also can work well :

I put the two .exe and the ralted files into one folder, then generate .sb file :

I attached all the files.

And please erase the flash to have try refer to "Kinetis Bootloader QuadSPI User's Guide.pdf"

Have a great day,
TIC

Ah you're right -- I need to erase the memory before it can be written -- thank you!
