void itm_init | ( | void | ) |
Target specific initialization function.
This function is responsible for initializing and configuring the debug clock for the ITM and setting up the SWO pin for debug output.
The only Cortex-M register that should be modified is the clock prescaler in TPI->ACPR.
The generic mbed_itm_init initialization function will setup:
ITM->LAR ITM->TPR ITM->TCR ITM->TER TPI->SPPR TPI->FFCR DWT->CTRL
for SWO output on stimulus port 0.
void mbed_itm_init | ( | void | ) |
Initialization function for both generic registers and target specific clock and pin.
uint32_t mbed_itm_send | ( | uint32_t | port, |
uint32_t | data | ||
) |
Send data over ITM stimulus port.
[in] | port | The stimulus port to send data over. |
[in] | data | The 32-bit data to send. |
The data is written as a single 32-bit write to the port.
void mbed_itm_send_block | ( | uint32_t | port, |
const void * | data, | ||
size_t | len | ||
) |
Send a block of data over ITM stimulus port.
[in] | port | The stimulus port to send data over. |
[in] | data | The block of data to send. |
[in] | len | The number of bytes of data to send. |
The data is written using multiple appropriately-sized port accesses for efficient transfer.
