Conditions for disabling time-out detection

[masahirokiniwa]

Could you tell me conditions for disabling time-out, when I use KL03 ROM bootloader.

When boot-pin is asserted or user-application is not valided, ROM bootloader disable time-out detection.
It's wrote at KL03 reference manual Rev.4 P.113 Figure 11-2.
But ROM bootloader disabled time-out detection at another situation, when I ran it from my user application.

I ran bootloader by below sequence same as RM P.114 11.3.5.
// Read the function address from the ROM API tree.
runBootloaderAddress = **(uint32_t **)(0x1c00001c);
runBootloader = (void (*)(void * arg))runBootloaderAddress;
// Start the bootloader.
runBootloader(NULL);

And I set BCA as below.
tag = "kcfg"
enabledPeripherals = use only I2C
i2cSlaveAddress = 0x50
peripheralDetectionTimeout = 10000 (10s)

Could you tell me what happened for disabling time-out.

Hi Masahiro,

if you call the bootloader explicitly from your application, there is no timeout. So if you call the bootloader from your application, it stays in the bootloader until you do a reset.

Timeout is only used if bootloader is entered automatically after reset.

See other details in Getting Started: ROM Bootloader on the NXP FRDM-KL03Z Board | MCU on Eclipse .

I hope this helps,

Erich

Hi Erich

Thank you for your answer.

I saw a reason of this case.
