Hello,

At first, I'm sorry if I ask beginner questions but I haven't any experience with flash programming.

I want to download a simple program and execute into NOR flash on my MCB1800 board with an Lpc1850 on.
The NOR Flash is a Spansion one with the following ref : S29GL064N

For this I find the application note number "11285" about "Writing a flash programming algorithm for unsupported devices" where they provided a flash driver for my board.

I place it into "lpcxpresso_dir/bin/flash" and try to use it.

The download bar went to 100% and they don't report any error. When I check the memory to check if the code is in, it is.

But when the download finished, nothing passed. The code don't execute and I have this message : "No source available for "0x1040683c" "

Is it something specific to do for start execution from NOR Flash ?

I'm using LPCXpresso v.5.2.4 Build 2122 on a Windows 7 64bits, with full licence type.

Did you read this FAQ?
http://support.code-red-tech.com/CodeRedWiki/LPC18xx_43xx_ExternalFlash

Also, you need to configure your project to use the external flash (by default it will use internal RAM). Links are in the above FAQ.

Yes I manage the memory configuration to add my EXT32 NOR Flash on location "0x1c000000" with a size of 0x100000.

Or you are telling about "Enhanced Managed Linker Scripts" ?

There is something like macro in IAR for lpcxpresso ? For write memory before the execution of the code ?

We supply a number of prebuilt SPIFI drivers, which have the filename format of:

LPC18_43_SPIFI_<flashsize>_<sectorsize>.cfx

The "biggest" we currently supply is for 8MB parts with 64KB sectors. From a very quick skim of the datasheet for the S29GL064N, it looks like it is 64MB with 64KB sectors.

I would expect that you would probably be able to program the first 8MB of this flash with the 8MB driver that we supply - [FONT=Courier New]LPC18_43_SPIFI_8MB_64KB.cfx[/FONT]

Try selecting this driver and programming a simple test image. Does it work? If not then post the debug log...

http://support.code-red-tech.com/CodeRedWiki/DebugLog

But if it does work, then try adding a new build configuration to the SPIFI flash driver project that we supply in LPCXpresso with the appropriate size settings. You can find this project in the [FONT=Courier New]LPC18xx_43xx_SPIFI.zip[/FONT] at:

[FONT=Courier New]C:\nxp\LPCXpresso_5.2.4_2122\lpcxpresso\Examples\FlashDrivers\NXP\LPC18xx_43xx[/FONT]

You'll need to read this FAQ first though...

Looks like you are building your image incorrectly. SPIFI flash is located at a base address of 0x14000000, not 0x1c000000.

If I manage the memory configuration for try to download code into spi flash memory I get the same error with different value.

Here is the error :

Nothing could be wrong with it ?

So if you are using the MCB1800 board, can you confirm whether your board has an LPC1857 or LPC1850 MCU fitted?

If it has an LPC1857 fitted, then select this as your target MCU and use the internal flash.

If it has an LPC1850 fitted, then first of all check the boot pins...

http://www.keil.com/support/man/docs/mcb1800/mcb1800_su_configuring.htm

It would then be worth trying to program the 4MB SPI flash that the board has fitted...

http://www.keil.com/mcb1800/specs.asp
http://www.keil.com/mcb1800/MCB1800v1-3-schematics.pdf

From the schematics, it looks like this is the same device as used on the NGX Xplorer boards, in which case you could use the LPC18_43_SPIFI_4MB_64KB.cfx flash driver supplied in LPCXpresso.

Hello,

I have an lpc 1850 on the board, the jumper are right for boot from spifi.

When I try to debug I always have this error tell that cannot access memory at 0x14003b90.

But this time I have this on the debug console :

and here is the debug log message :

If the gdb traces can also help you to find the issue, I can send too.

But the first thing I want to do isn't to program spifi flash memory. I want to copy and execute my code in external NOR Flash. Where the base address is 0x1c000000.

Because in future project I have to use spifi for another goal.

Is there something for initialize pins for the correct memory (SPIFI Flash or NOR Flash) Before executing code? (Like the macro in IAR.)

When this error occurs, i think it looks like the MCU cannot access memory beacause related pins aren't set up.

From your debug log, it looks like you are using LPC-Link2. Unfortunately we don't currently support this as a debug probe for LPC18 targets. For more details please see:

http://support.code-red-tech.com/CodeRedWiki/LPCLink2support

You'll need to use an original LPC-Link (ie a split LPCXpresso board) or else a Red Probe+.

Yes I'm using an lpc-link2. Thank you for the explanation I don't hear about that before.
I will test with an lpc-link shortly and give you a feed back.

I try with the lpc-link to load and execute my code in SPIFI and it's working fine.

But about the NOR Flash, it's still impossible to download and execute my code correctly. I don't know why but when the application start, the Memory located at 0x1c000000 isn't available. But after when I try to run the driver to see what is in the memory after initialization I can see my code in.

the new debug log indicate an error which I'm not familiar with.

You did remember to switch your boot config pins back after running from SPIFI ?

HTH!

Yes I have done this. I switch back for EMC32 bits.

Why the memory could not be accessible. When I see the memory in debug mode at beginning of the application, there is only "1" or "F" in hexa.
After if I test the driver in debug mode, and pass the initialization pin to access the memory, I can see my code in.

No idea about what could be provoked this ?

So if you run the debug driver's debug build configuration (which downloads the basic driver into RAM from a "standard debug session", can you check that it first of all erases and then programs the flash memory?

Might be worth you just exporting and posting your flash driver project.

Hi,

Yes I have test in debug mode, and all the functions are working fine.
Sorry for the late answer, I was in holiday 2 days.

The project is export in attached file. I have to clean it because it was too large.

Kind regards

Hi,

When I start debug the application, I see in the memory that there is only "1". But when I test an other little program just to init the memory, I can see my code in.

Is it possible to write something in the memory before starting the application ? Because I have to write some register after each reset to enable the memory controller.

Kind regards,
Maxime
