Tool/software:
To whom it may concern,
I have downloaded threadx porting code from https://github.com/TexasInstruments/mcupsdk-core.git
I've successfully ported threadx on TMDS64EVM board.
After porting R5F core, I noticed that there is floating point print issue.
Before threads start in main function, if I put the following code,
main()
{
float a = 3.0f;
DebugP_log("[R5_0] R50 float value %f !!!\r\n",a);
/* Enter the ThreadX kernel. */
tx_kernel_enter();
}
it printf "[MAIN_Cortex_R5_0_0] [R5_0] R50 float value 3.000000 !!!" No issue on floating point print.
Buf after thread execute at thread entry function, the float variable prints weird value.
void tx_application_define(void* first_unused_memory)
{
UINT status;
status = tx_thread_create(&main_thread, /* Pointer to the main thread object. */
"main_thread", /* Name of the task for debugging purposes. */
threadx_main, /* Entry function for the main thread. */
0, /* Arguments passed to the entry function. */
main_thread_stack, /* Main thread stack. */
MAIN_TASK_STACK_SIZE, /* Main thread stack size in bytes. */
MAIN_TASK_PRI, /* Main task priority. */
MAIN_TASK_PRI, /* Highest priority level of disabled preemption. */
TX_NO_TIME_SLICE, /* No time slice. */
TX_AUTO_START); /* Start immediately. */
}
void threadx_main()
{
float a = 3.0f;
DebugP_log("[R5_0] R50 float value %f !!!\r\n",a);
}
In threadx_main function, it prints the value as follows,
"[R5_0] R50 float value 32.000008 !!!"
I have enabled, FPU context switching by define TX_ENABLE_FPU_SUPPORT feature but no luck.
Please let us know what part of the code I have to modify.
Thank you,
Sangjoon
