Hi everyone,
My custoer does not want to implement the JTAG circuit on production board and he want to update only CAN port.
So I suggested to him to write CAN boot loader before board mounting of the device(TMS570LS313).
Then please let me following questions.
Q1.
Are there any application note for writing two project(boot & app) in a single device?
My custoer don't want to erase the CAN boot code but Example project of the following link may erase the CAN boot code.
processors.wiki.ti.com/.../TMS570_Hercules_MCU_Bootloader
Q2.
If he remove JTAG circuit and write programs with CAN port,
Which do you recommend (A) and (B).
(A) every time load the boot code
(B) protect the boot code (using Flash Bank Sector Enable Register) and to only load the application code.
I want to suggest an easy way to my customer.
Best regards,
Sasaki
