I'm using keil5 to develop KEA128 chip, I want to know how to do the boot software and app software.Can you help me?
Please let me know what KEA128 board you used? The NXP board or your customer board?
It's our customer board.
I find some other IDE's bootloader project.I know how to jump from bootloader to application.But how to set the interrupt vector in the application?
There are also KEA128 boot loaders here:http://www.utasker.com/kinetis/TRK-KEA128.htmlhttp://www.utasker.com/kinetis/FRDM-KEAZ128Q80.html
A guide to application/ bootloader compatibility can be found in the appendix of its user's guide: http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.PDF
To enter interrupt sat the application there are two methods:- leave in Flash and set the VBA to the flash location (must be on a 256 byte boundary for KEA128)- enter in SRAM and set the VBA to the SRAM address (same alignment requirement).
In the uTasker project RAM based vectors are entered with (for example):fnEnterInterrupt(irq_I2C0_ID, PRIORITY_I2C0, _I2C_Interrupt_0);
