LPC4357 Dual-Core programming error

When programming the LPC4357 using a Red Probe+ and LPCXpresso 5.2.4 I get an exit error when programming the device from the GUI tool. The command line tool just hangs (at the same point).

First the flash area of the M4 (Flash A) gets programmed successfully, then the flash area of the M0 core (Flash B) gets programmed (also successfully). And then area just after the first Flash A gets programmed (only 76 bytes @ address 0x1A0016DC). But this is the points where the trouble starts.

I get an exit code -1073741819

I use this command:

crt_emu_lpc18_43_nxp -g -2 -vendor=NXP -pLPC4357 -s1000 -flash-load-exec "D:\dual_core_test\M4app\Debug\M4app.axf"

What is going wrong here?
Strangely enough everything goes well when entering a debug session on the M4. Both Flash A and B get programmed, but the last area (where the errors are) is ignored. After a manual reset the program works fine, even without debugger.

BTW, version 5.2.2 of LPCXpresso shows no error programming, however the code itself does not run properly. Only when I first invoke a debug session (which includes automatic programming/flashing) the code runs properly afterwards (e.g. after reset/no debugging active). This is this case for both 5.2.2 and 5.2.4. Anybody from Code Red knows the cause maybe? What are the differences in programming/flashing between the debug session and the GUI tool.

I realized I have posted the .axf file of LPCXpresso 5.2.2. This post contains both versions (M4app_5.2.2 and M4app_5.2.4) as well as the dual-core MCB4357_blinky example which also has the same flashing/programming error.

Hello CodeRedSupport,

I have made a new LPC4357 board design and tested the dual core programming behaviour on this new board also. Unfortunately the result is the same. Therefore I think the problem is not related with the hardware. Strangely enough the programming goes well when initiating a debug session on the M4. After a hardware reset the program is running fine (also during deguggint by the way). Why would 'normal flashing' be different from the flashing performed prior to debugging?

I have a lot a dual-core coding to do, so I really need the direct flashing option.

At present, as you have already noted, using the Debug button will correctly program the flash. Thus whilst we investigate you will need to use this method of programming flash rather than the GUI flash programmer.

Hmm I have to come back one the previous post it seems... Flashing the MCU with the flash tool is still not working correctly with v5.2.6. Also flashing using debugging is becoming a problem too. I get the following error in, let's say, 20-40% of the debug sessions:

Flash driver ProgramPage return code: 0x1

It is a dual core application (bankA for the M4 and bankB for the M0). I also use USB functionality (NXPUSBLib from LPCOpen). I get the feeling that the dual core nature and the USB code have to do something with these errors.

@Code Red Support: do have already have located the problems from the earlier .axf file?

IIRC the problem that you reported before was simply an issue with the way the IDE was invoking the GUI flash programmer for these parts.

To look into your current programming issue, please can you post the debug log:

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

and assuming that you aren't in a position to post an example application with which you see the issue...

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

...can you please also ZIP up and attach the map file and AXF from your application. Can you also confirm which version of LPCOpen / NXPUSBLib you are using?

I've tested out the programming of your application to a Keil MCB4357 board here. The board works fine using a set of other test images, until I program in your image. After starting a debug session with your image, I start getting connection errors and the only way to recover the board so that I can program a different image in is to boot the board into ISP mode:

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

By booting in ISP mode, then setting a breakpoint at the start of ResetISR in your image (by changing the initial breakpoint in the launch configuration from 'main' to the address of ResetISR ('*0x1a002eb8'), I can successfully program your image and then start to step through its initialisation sequence.

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

Tracing this through, I can see that the debug connection is lost when the call chain reaches:

ResetISR -> SystemInit -> SystemSetupClocking -> Chip_Clock_SetBaseClock

Thus it looks like something in your clock setup code is killing the debug connection.

Hello lpcxpresso-support,

Thanks for the test.

I guess you get that error since my board is using an external clock buffer which is routed to the GP_CLKIN pin instead of the crystal input. Changing the clock source of the core from the interal resonator to the clock input pin causes the debugger to lose connection I guess (there is no clock anymore after all in case of the Keil board, which uses a crystal).

My apologizes, I forgot to mention this. Did not realize it at the time of posting...

BTW this is the SystemSetupClocking function:

STATIC void SystemSetupClocking(void)
{
int i;

Chip_SCU_PinMuxSet(0xF, 4, (SCU_MODE_MODE_PULLDOWN | SCU_MODE_INBUFF_EN | SCU_MODE_ZIF_DIS | SCU_MODE_FUNC1));

/* Setup FLASH acceleration to target clock rate prior to clock switch */
Chip_CREG_SetFlashAcceleration(MAX_CLOCK_FREQ);

/* Switch main system clocking to external pin */
Chip_Clock_DisableCrystal();
Chip_Clock_SetBaseClock(CLK_BASE_MX, CLKIN_CLKIN, true, false);


/* Setup PLL for 108MHz and switch main system clocking */
Chip_Clock_SetupMainPLLHz(CLKIN_CLKIN, CRYSTAL_MAIN_FREQ_IN, 108 * 1000000, 108 * 1000000);
Chip_Clock_SetBaseClock(CLK_BASE_MX, CLKIN_MAINPLL, true, false);
emc_WaitMS(10);

/* Setup PLL for maximum clock, 204 MHz */
Chip_Clock_SetupMainPLLHz(CLKIN_CLKIN, CRYSTAL_MAIN_FREQ_IN, MAX_CLOCK_FREQ, MAX_CLOCK_FREQ);
emc_WaitMS(10);

/* Setup system base clocks and initial states. This won't enable and disable individual clocks, but sets up the base clock sources for each individual peripheral clock. */
for (i = 0; i < (sizeof(InitClkStates) / sizeof(InitClkStates[0])); i++) {
Chip_Clock_SetBaseClock(InitClkStates.clk, InitClkStates.clkin,
InitClkStates.autoblock_enab, InitClkStates.powerdn);
}


/* Setup USB0 PLL state for a 480MHz output and attach */
LPC_CGU->PLL[0].PLL_CTRL |= 1; // Power down PLL
LPC_CGU->PLL[0].PLL_NP_DIV = (98<<0) | (514<<12);
LPC_CGU->PLL[0].PLL_MDIV = (0xB<<17)|(0x10<<22)|(0<<28)|(0x7FFA<<0);
LPC_CGU->PLL[0].PLL_CTRL = (CLKIN_CLKIN<<24) | (0x3<<2) | (1<<4);
Chip_Clock_SetBaseClock(CLK_BASE_USB0, CLKIN_CLKIN, true, false);


/* Setup CLKOUT */
Chip_Clock_SetDivider(CLK_IDIV_E, CLKIN_MAINPLL, 10); // Divider E = 10
Chip_Clock_SetBaseClock(CLK_BASE_OUT, CLKIN_IDIVE, true, false);
}

Strange thing about these problems is that it is only happening once in a while.

So if you boot into ISP mode before attempting to program, does that help?

Or if you set the vector catch option in your launch configuration, does that help?

And if you try changing the clock setup to "something more simple", does that help?

I think I have found some sort of solution, or at least an improvement. I have changed the SDRAM clock divider from 2 to 1, e.g. now it runs in sync with the M4 core. And I have lowered the main clock from 204 MHz to 156 Mhz. This was necessary since the SDRAM can only run up to 160 MHz. Unfortunately this cost me some performance, but the programming of the flash seems to work OK when invoking a debug session. Still programming using the flash tool is not going well. But I can live with that.

Regarding the debug configuration: I have set the XTAL and PLL values to '12000, 72000' in the Target Configuration settings. The 12000 corresponds well with the crystal I use (although not connected to the crystal inputs but to the GPCLKIN pin). But the PLL value is way off (it should be 156000 obviously). Strangely enough I get an error saying that the PLL value in incorrect. Why can’t I set the correct PLL value? I seems although that debugging works ok.

In what way is it not going well? Can you provide details, including the log from a programming failure? Did resetting your board into ISP mode before attempting to program the flash, as I suggested previously, make any difference?

These debug configuration options do not apply to these parts (which I'll flag as needing to be made more obvious in a future release). The flash driver will simply reset the clock to use the IRC.

Using LPCXpresso 5.2.6 does no give any error using the flash tool. See also earlier post. Using 5.2.4 causes the tool to hang wrting the last block. But if I understand correcty this had something to do with the call to the tool inside Eclipse and has been fixed. Version 5.2.6 does flash completely but the firmware does not run properly. Flashing after ISP is invoked on the board seems to work better (not 100% sure yet). For the mean time I rely on flashing with the debugger. One thing I noticed is that the flash tool flashes in blocks of 4096 bytes and via GDB 32768 at a time.

Ah that explains why there is no difference in setting these values or not. Thanks.

I'm not sure what you are looking at here, but you are basically using the same flash driver under both the debugger and the GUI flash tool. Thus these will both program in 4KB blocks.

If booting into ISP mode before programming flash more reliable (either via the GUI flash programming tool or via the debugger), this would indicate that something in the way you are setting the clock up in your code base is preventing the flash driver functioning correctly.

I've attached a new version of the flash driver file which has a subtle change in its initialisation sequence which might work around this clock issue. Please can you unzip this and drop the .cfx into the /bin/Flash subdirectory of your lpcxpresso installation and let us know if you see any change in behaviour. You might want to back up the original first.

The external memory controller on the LPC4357 cannot be run over 120MHz. See Tcy(clk) in the data sheet.

Also be aware that there is a new errata concerning problems with divide by two mode on the external memory controller: http://www.nxp.com/documents/errata_sheet/ES_LPC435X_3X_2X_1X_FLASH.pdf

Also be aware that there is a new errata concerning problems with divide by two mode on the external memory controller: http://www.nxp.com/documents/errata_sheet/ES_LPC435X_3X_2X_1X_FLASH.pdf

Thanks for pointing that out. This explains the strange behaviour I have seen during SDRAM access. The only situation for which this is relevant is when the cpu(s) run at 204 MHz and consequently the EMC at 102 MHz. Unfortunatly that is where I was.

Running them at 156 MHz seems to work well despite the 120 MHz statement.

I think it is best to go to 192/96 MHz for now.

BTW still have to test the flash driver.
