Bootloader problem Using CW 10.2 with MQX 3.8 on a Kinetis K60 !

[monXii]

Hello all,

i tried to use the FNET bootloader with MQX .. followed the user guides to modify the linker files and so on..

but when FNET flashes the MQX application and tries to start it, K60 restarts every time ..

then i wrote a little bootloader myself which updates an *.s19 from an sdcard ..

tries to start the MQX application .. restarts every time ..

then i debugged with LEDs in the MQX .. the application itself starts .. entry point is ok ..

the last debug i see on my leds i before this line:

_sched_start_internal();   /* WILL NEVER RETURN FROM HERE */

and main_task is not started ..

and after _sched_start_internal() is only assembler andits really difficult to debug ..

some here use an bootloader with an MQX main application .. ??!

thanks so far!

Are you saving the new entry point before restart it? Try with "save" before restart, if you didn't

I don't have any problems with FNET and MQX (I use MCF52259 but it isn't too different)

mh, save entry point?

when i upload the s19, FNET tries to start the flashed app automaticly ..

and fails with this ..

What is the address of your MQX entry point? Is the address bigger than 0x0000C420?

Did you re-compile bsp and psp adding #define MQX_ROM_VECTORS          0 in user_config.h?

Did you modify correctly lcf of your MQX project? You can see that in .xMap generated by CW.

I followed these steps and it worked perfectly with Hello_Wold example.

By the way, you need to save the new entry point unless you have a script in your boot mode.

I hope it helps you

yes address is bigger ..

entry point -> __boot -> @ address 0x0000DF40

yeah, i have recompiled both with this define ..

xMAP looks like the application node ..

here the relevant snippet :

and the "save" command is in the script ..

#define FAPP_CFG_TFTPS_AFTER_WRITE_REQUEST_SCRIPT   "set boot go; save; go"

[matute]

I see a difference between your .xMap and .xMap of AN4367:

your .xMap

#>0000C000          __VECTOR_TABLE_ROM_START (linker command file)
  0000C000 00000400 .vectors_rom rom_vector    (bsp_twrk60n512.a vectors.o      )
  0000C000 00000000 .vectors_rom .vectors_rom    (bsp_twrk60n512.a vectors.o      ) 

AN4367 .xMap

#>0000C000          __VECTOR_TABLE_ROM_START (linker command file)
  0000C000 00000410 .vectors_rom rom_vector    (bsp_twrk60n512.a vectors.o      )
  0000C000 00000000 .vectors_rom .vectors_rom    (bsp_twrk60n512.a vectors.o      )

See your lcf if you realy define this line

vectorrom   (RX): ORIGIN = 0x0000C000, LENGTH = 0x00000410

It seem that you have LENGTH = 0x00000400 at this line of lcf

yeah .. i saw this too..

but its defined like AN ..

fnet_bootloader  (RX) : ORIGIN = 0x00000000, LENGTH = 0x0000C000
vectorrom          (RX) : ORIGIN = 0x0000C000, LENGTH = 0x00000410
rom              (RX) : ORIGIN = 0x0000C420, LENGTH = 0x0007F000-0x0000C420

don't know why he only uses 0x400 bytes ..

and the ram vector table is 0x418 bytes big .. ?!
