Problem running AN2295

feraro — Wed, 16 Oct 2013 07:02:56 GMT

Hello.

I downloaded the project "AN2295_Kinetis" KINETIS K 100MHz. I try to run on my board with MK60DN512 in debugger mode, and when it enters the while (1) to await receipt of characters from the serial port, the debugger gives the error:

ARM Processors, AN2295_Kinetis.afx (Suspend)
Thread [ID: 0x0] (Suspended: Signal 'Halt' received. Description: User halted thread)
1 0xE0B003E8 (0xE0B003E8) () 0xe0b003e8

The project is the original Freescale. I'm using in my board the UART3 to conect with PC.

I've also noticed that when I run the program win_hc08sprg.exe attempts to detect the target, nothing is coming out the computer's serial port.

Someone can help me?. Thanks in advance.

Greetings.

Fernando

Hi Fernando,

The TWR-K60N512 board provides two serial port connection, one is on board OSBDM (USB CDC serial port UART5), the other one need to connect with TWR-SER board (UART3).

For the AN2295 is using UART3, which need to use serial port on TWR-SER board. And I check the latest AN2295 software, the baud rate is 9600.

Wish it helps.

Hi Hui_Ma.

Thanks for the reply

I'm testing with the Tower and the serial port UART3. I have win_hc08sprg.exe program, set to 9600 baud and marking Short TRIM. Now show me the following message: "The maximum attemps to try calibrate clocks reached. Baudrate Try again with diffrent settings.".

I tried with different baud setting, but some do not receive the ACK and other continuous showing the same message.
What can be the reason for this?

Regards.

Fernando

Hi Fernando,

What silicon revision are you using in your board?

K60N512 config supports two silicon revisions:

#define KINETIS_MODEL K60_100MHz

//#define KINETIS_K60_OM33Z

By default would be Rev1.x

And for silicon 2.x you should use K60D100.

There are some small differences but those differences make the project to work or not to work.

Hi Luis.

The silicon version is K60_OM33Z. And the revision is 1.0. I'm testing with TWR-K60N512.

Best regards.

Hi,

Then, Have you changed the #define in the configuration file?

Luis

Re: Problem running AN2295

feraro — Thu, 17 Oct 2013 16:09:19 GMT

Hi Luis.

Yes, I have done the following:

/ / # define KINETIS_MODEL K60_100MHz
# define KINETIS_K60_OM33Z

But when I build the project generates 86 errors.

So what we've done is, in the file bootloader_cfg.h

/ / # Include "AN2295_TWR_K60_cfg.h"
# include "AN2295_TWR_K60D100_cfg.h"

The errors are solved. But when I run the program, it jumps to the function
Boot_ResetMCU()

I do not know what to do.

Hello Ramon,

Please uncomment both defines, so in the file TWR_K60_cfg you should have:

# define KINETIS_MODEL K60_100MHz

# define KINETIS_K60_OM33Z

And change in bootloader_cfg.h the include to the correct one:

# Include "AN2295_TWR_K60_cfg.h"

//# include "AN2295_TWR_K60D100_cfg.h"

Now it should work.

Let us know if it solves your problem.

Regards,

Santiago

Thank you very much for your help.

That was it.
Had misunderstood the directions of Luis.

Thanks Luis and Santiago.

Hello again.

The tower is working properly.

However, I record it on my board and still not working.

The only difference between my board and the tower is that in my board, micro mask is 8N30D, and the frequency of this oscillator is 8 MHz instead of 50 MHz of the tower.

I think the problem may be in the BOOT_BUS_CLOCK value, but I do not know what value I enter.

Best Regards.

Fernando

Hello,

Try uncommenting the 0M33Z define.

Hi Santiago.

This define is uncommented. I did to make it work in the tower.

Best Regards

Fernando.

santiago_gonzal — Fri, 18 Oct 2013 08:01:40 GMT

Sorry,

I meant "Comment it". This define fixes the bus clock, and makes it work with the 0M33Z mask. For your mask, you should comment it.

Hi.

I also tried it and still not working.

The problem is that the board does not return the ack.

Could it be that the problem is in the calculation of the baud rate, using a 8 MHz oscilator?

Regards

Fernando

santiago_gonzal — Fri, 18 Oct 2013 12:44:58 GMT

Hello Ramon,

That shouldn’t be the problem, since the boot clock is configured to be the slow internal oscillator.

Are you using the same UART that is used in the TWR board to communicate with the PC application?

Regards,

Santiago

Re: Problem running AN2295

feraro — Fri, 18 Oct 2013 12:57:48 GMT

Hi Santiago.

Yes, it is the same, use the UART3 and working properly. My applicaction on this board is using the same UART to communicate with PC.

Regards.

Fernando

Hello
I have seen that data is received by the UART3, but when the application sends, nothing comes through the port. In the tower running, but not on my board.

Re: Problem running AN2295

feraro — Fri, 18 Oct 2013 14:26:35 GMT

Hello.
I think I've seen what the problem.

My board works in RS-485 and tower in RS-232, and the bootloader is not trying TX_ENABLED pin, being made for RS232. To see how I can fix it.

Thank you very much for all the help provided.

Best Regards

Fernando

Hello.

When I load the application with the bootloader, win_hc08sprg.exe program, displays the following message:

WARNING! S19 image will not fit into available memory (at address 0x00000400)!

Changes made to the file intflash.lcf of my application are as follows:

Originally:

vectorrom (RX): ORIGIN = 0x00000000, LENGTH = 0x00000410
rom (RX): ORIGIN = 0x00000420, LENGTH = Const 0x0007FBE0 # Code + data
ram (RW): ORIGIN = 0x1FFF0000, LENGTH = 0x00020000 # SRAM - RW data
cfmprotrom (RX): ORIGIN = 0x00000410, LENGTH = 0x00000010

After the changes:

vectorrom (RX): ORIGIN = 0x00000000, LENGTH = 0x00000410
rom (RX): ORIGIN = 0x00004410, LENGTH = Const 0x0003BBF0 # Code + data (0x00040000 - 0x00004420)
ram (RW): ORIGIN = 0x1FFF8000, LENGTH = 0x00010000 # SRAM - RW data
cfmprotrom (RX): ORIGIN = 0x00000410, LENGTH = 0x00000010

Can anyone tell me how I can fix it.

Thank you very much.

Regards.

Fernando.

Hello Fernando,

You don't need to change the linker file in order to use AN2295 bootloader. It will process the S19 and flash it in the correct place of Flash memory.

Try with the standar linker file,please.

Santiago
