How can i definition a const var in Banked Flash memory?

xiaoli — Tue, 08 Mar 2016 07:58:29 GMT

in prm file,

PAGE_38 = READ_ONLY 0x3880000 To 0x388FFF;

PLACEMENT:

constSec INTO PAGE_38;

Source Code:

constSec: SECTION

FDB $1234

FCB $55

Question:

Why at CSW, I can't see memory at addr 0x3880000, the value must be 0x123455.

Thank for your answer.

Hi,

Probably you're using CW for HC12 v5.1.

I've create a short example using the simulator and it seems to be working on my side.

Extract of the map file:

*********************************************************************************************

SECTION-ALLOCATION SECTION

Section Name Size Type From To Segment

---------------------------------------------------------------------------------------------

.init 11 R 0xC000 0xC00A ROM_C000

.startData 10 R 0xC00B 0xC014 ROM_C000

.copy 2 R 0xC015 0xC016 ROM_C000

.text 56 R 0x208000 0x208037 PAGE_20

constSec 102 R 0x388000 0x388065 PAGE_38

.stack 256 R/W 0x800 0x8FF RAM

Attached you will find the example.

Have a great day,

Hi,

In your asm file you defined:

EEPROM_DATA: SECTION

DEFAULT_4000: SECTION

DEFAULT_C000: SECTION

OTHER_ROM: SECTION

In prm file there are:

DEFAULT_4000 and DEFAULT_C000

INTO ROM_4000,ROM_C000; /* ROM_4000*/

OTHER_ROM INTO PAGE_38, PAGE_39, PAGE_3A, PAGE_3B, PAGE_3C, PAGE_3D;

EEPROM_DATA INTO EEPROM;

This is the debugger launched in simulator mode:

Thanks for your answer.

i have try ,and let the debugger launched in simulator mode. The result is the same as what you said.

But the same project, the debugger launched in "debug" mode, The result is the same as what i said before. There is nothing(even have,just 0xFFFF) ad addr page0x38. so, That's the point.

so, What can i do, i need to into debug mode, and get the right value what i wanted, the right value as the debuger show.

waiting for your answer.

Thank you again.

Hi,

I've a 9s12DP512 device and P&E USBMultilink interface.

Using your project, I selected the P&E USB BDM Multilink and build the project.

After that I launched the debugger and select my device ... it's working fine.

Please have a look to the video attached.

Dear Pascal Irrle:

i have read the *.mp4， Thank you very much. But my project it's truly have problem. and i check the cmd window.

There is a Red line like this:

FP: All_PPAGES flash module is bad or protected.

executing .\cmd\P&E_Multilink_CyclonePro_vppoff.cmd.

and maybe that's the problem.

and i have try another project in the same hardware, there havn't this red line. So, did you know how can i fixed this?

Thank's a lot.

and i have Baidu, someone has the same problem like ：see http://bbs.eeworld.com.cn/thread-323665-1-1.html .

so, can you help?

Hi,

Unfortunately I don't have a DP256 device.

Now if I select the DP256 device (MCUID 0x3c6), I got similar error with my DP512 device.

I've found an old message with a colleague regarding the Dx256 devices.

In fact the DT256, DP256, DJ256, ... were very similar.

Different MCU_ID were used but the files are similar.

Please have a look to the \CWS12v5.1\Prog\fpp folder.

DP256 -> Mcu03c6.fpp

DJ256 -> Mcu03d8.fpp

DT256 -> Mcu02ea.fpp

DT256B -> Mcu03d7.fpp

You can open them using notepad for instance and you can see all files are identical.

I've a DT256 and I tried with this device.

I got the in Command component:

The project using DP512 generates similar problem whereas with DT256 device it's working fine.

I don't think there is a problem with the fpp file as it's working fine on my side.

Does the problem is linked to the interface ?

Please can you provide me the same command dialog you get on your side.

It could be interesting to compare the flash version used.

Another test you can do: select DP512 instead of DP256.
