MKW30Z rebuild Bootloader OTAP for new PCB layout

framework\Bootloader\Bootloader_OTAP_Serial

What hardware changes on new PCB will trigger a rebuild on the Bootloader_OTAP_Serial ?

If NO RTC 32KHz external quartz oscillator on new PCB then the boot loader code must be changed ?

Thank you,

Lucian

Project location framework\Bootloader

Target selection in project

or

pastedImage_3.png

Some parameters:

MCU_MKW40Z160
gEepromType_d=gEepromDevice_AT45DB021E_c

pastedImage_4.png

so gEepromType_d change should trigger a rebuild.

/* List of the EEPROM devices used on each of the FSL development boards */

gEepromDevice_None_c          0
gEepromDevice_InternalFlash_c 1
gEepromDevice_AT45DB161E_c    2 /* TWR-KW2x */
gEepromDevice_AT26DF081A_c    3 /* TWR-MEM */
gEepromDevice_AT45DB021E_c    4 /* TWR-KW4x*/

What about MCU change type from MCU_MKW40Z160 to MKW30Z  ?

Linker gRomSize_c=0x28000 param

pastedImage_9.png

other parameters might be:

gEepromParams_WriteAlignment_c, gEepromWriteEnable_d, gSerialBootloaderEnable_c,
gSPI_HW_TYPE_c, gSerialBootloaderEnable_c, BOOTLOADER_CRC_ENABLE, BOOTLOADER_ENABLE_VERIFY,
BOOTLOADER_ENABLE_READ_CMD, BOOTLOADER_INT_WATCHDOG  

What other HW PCB changes may trigger boot-loader re-builds ?

What about NO RTC 32KHz external quartz oscillator on new PCB ?

Thank you,

Lucian

32KHz XTAL is not a requirement for the bootloader, so, you're safe on that end. But, you'll loose some low power capabilities.

Here're some scenarios the will requiere a bootloader re-build:

- Any change in the bootloader configuration

- Use different IC

- Use a different SPI module

- Use different pins

- Use different memory

- Add extra functionality
