How to apply BCA configuration?

masahirokiniwa — Mon, 31 Jul 2017 02:45:56 GMT

I try to run the KL03 ROM bootloader from user application with BCA configuration.

I set to BCA about below configurations, but I looked like it was not applied.

- tag

- enablePeripherals : use only I2C

- i2cSlaveAddress

- peripheralDetectionTimeout

- clockFlags and clockDivider

I saw that the time-out is not applied when user application call ROM bootloader.

1. When user application call ROM bootloader, BCA configuration is not applied to it like time-out?

2. How to apply BCA configuration when I run ROM bootloader from user applicaiton?

Best regards,

Maybe this article helps you:

Getting Started: ROM Bootloader on the NXP FRDM-KL03Z Board | MCU on Eclipse

And yes, if you call the bootloader from the application, the timeout is not applied, but everything else is (from what I can tell using blhost). You would have to implement that timeout in the user application part. Or you could setup a watchdog as timeout.

I hope this helps,

Hi Erich

Thank you for your answer.

I would like to know how to inirialize peripheral setting like I2C slave address and clock configuration.

When I run ROM bootloader from user application, is ROM bootloader doesn't initialize sewuence like a 1st column of Figure 11-2 in KL03 reference manual?

And, ROM bootloader keep the HW configuration by user application?
