LPC55S16 ThreadX Secure Boot Runtime Error

rjmalmeida0 — Thu, 15 Feb 2024 09:33:58 GMT

Hello everyone,

I developed a simple application for LPC55S16 platform with ThreadX that blinks the blue LED every second. During debug and after board reset, all works fine: the LED blinks and the debug UART also logs data.

The next step I tested was secure boot flashing using the MCUXpresso Secure Provisioning tool. I booted the board on ISP mode and connected to it through UART w/ 57600 baud. I selected "Plain" on Boot tab and built the image with a Success status. Then I flashed the image on the "Write Image" tab (as shown in the screenshot). The log shows success, as shown below:

After reset, the application does not start tho. The initializations are shown correctly but the threads do not run. Here's an example of the thread the blinks the blue LED:

/** * @brief Main application task * * args null */ void thfnc_DFRBMngmnt(VOID *args) { (void)args; PRINTF("starting thfnc_DFRBMngmnt...\r\n"); /* Main entry */ UINT status = TX_FALSE; UINT counter = 0; while (1) { /* Increment counter */ counter++; /* Send message to transmission queue */ status = tx_queue_send(&thq_TxQueue, &counter, TX_WAIT_FOREVER); /* Log message */ PRINTF("thfnc_DFRBMngmnt::sent message...\r\n"); /* Toggle LED */ GPIO_PortToggle(GPIO, BOARD_LED_PORT, 1u << BOARD_LED_PIN); /* Sleep for 1 second */ tx_thread_sleep(1000); } }

No UART logs nor the LED blinks.

Is this a ThreadX configuration or am I doing something wrong?
Any help would be nice,
Rui

Hello @rjmalmeida0

How about first test with a simple led project without ThreadX?

About using MCUXpresso Secure Provisioning Tool, please refer to "LPC55(S)0x/1x/2x/6x device workflow" of <MCUXpresso Secure Provisioning Tool user guide>.

Hello,

With a simple application without ThreadX the secure provisioning works fine.

Kind regards,

Rui

Hello @rjmalmeida0

How about reading data out then comparing with programed image?

And which IDE do you used? How about using IDE program? Also compare the two value using two method programed.

Have you tried to replicate the problem?
I created another project for the same platform, a little more complex one. Still, same behaviour.
