HALCoGen RM48L950ZWT for FreeRTOS 8.2.0

Lars von Wachenfeldt

Other Parts Discussed in Thread: HALCOGEN

Hi,
when do you plan to release the HALCoGen for FreeRTOS 8.2.0?

Or can I make my own changes in the files which are created by the current version of HALCoGen which supports FreeRTOS 8.1.2? The reason is that the code crashes when I use the new feature in FreeRTOS 8.2.0. - task notifications. I don't know the reason but it happens in this macro:

os_portmacro.h:
#define portYIELD_WITHIN_API() { portSYS_SSIR1_REG = portSYS_SSIR1_SSKEY; asm( " DSB " ); asm( " ISB " ); }

The strange thing is that it crashes the SECOND time it is executed.

Maybe you already have some working code which I could use (before the new HALCoGen release)?

Kind regards,
Lars

Hi again,
correction, it crashes the FIRST time the yield executes.

Thanks and regards,

Hi Lars,

What device are you running? Is it possible for you to share the code?

There is no immediate plan for HALCoGen to support 8.2.0. But certainly we could help you with a sample Blinky type of code.

Hi Prathap!
Yes, that would be great. Please mail the code.

I have discussion going on with the FreeRTOS engineers about the issue:

sourceforge.net/.../f50b9cb9

As I said to them, I might very well have messed up something but I cannot see it when I compare my 8.1.2 project with the 8.2.0 project (read the discussion for details - I've copied the project and overwritten the 8.2.0 FreeRTOS files but kept the HALCoGen files).

But please read the topic in the FreeRTOS forum for the history.

Kind regards,
Lars

Hi Lars,

A simple blinky code with FreeRTOS 8.2.0 on RM48x device.. 0081.RM48_RTOS_8_2.zip

Hi Prathap and thx for the code.

It stills crashes when using vTaskNotifyGiveFromISR and ulTaskNotifyTake though. :(

Please see this FreeRTOS forum discussion:

sourceforge.net/.../f50b9cb9

Maybe it has something to with the memory mapping and section configuration?

As I say (at the end of the FreeRTOS discussion), with this configuration (in sys_link.cmd) it works:

/* Memory Map                                                                 */

MEMORY
{
    VECTORS (X)  : origin=0x00000000 length=0x00000020
    FLASH0  (RX) : origin=0x00000020 length=0x0017FFE0
    FLASH1  (RX) : origin=0x00180000 length=0x00180000
    STACKS  (RW) : origin=0x08000000 length=0x00000200
    RAM     (RW) : origin=0x08000200 length=0x0003FE00
 }

/*----------------------------------------------------------------------------*/
/* Section Configuration                                                      */

SECTIONS
{
    .intvecs : {} > VECTORS
    .text    : {} > FLASH0 | FLASH1
    .const   : {} > FLASH0 | FLASH1
    .cinit   : {} > FLASH0 | FLASH1
    .pinit   : {} > FLASH0 | FLASH1
    .heap    : {} > RAM
    .bss     : {} > RAM
    .data    : {} > RAM
/*  .sysmem  : {} > RAM */
}

Do you have the possibility to test your code with vTaskNotifyGiveFromISR and ulTaskNotifyTake and see if it works?

1. vTaskNotifyGiveFromISR is executed

2. ulTaskNotifyTake is executed and returns true and works.

3. ulTaskNotifyTake is executed again and it crashes in portYIELD_WITHIN_API

Please see this FreeRTOS forum discussion for all of my code:

sourceforge.net/.../f50b9cb9

Kind regards,

Lars

Hi Lars,
it is maybe late, but have you tried disable the timers (tmr svc?)

Hi Szilárd!
Thx for the idea. I could try that sometime.

Kind regards,
