F28M35H52C: bootloader for M3-core and C-core

Rahul Ramachandran

Part Number: F28M35H52C
Other Parts Discussed in Thread: C2000WARE

Hi,

This is regarding the BOOTLOADER for F28M35x device.

We are looking bootloader for a concerto f28m35h52c(Dual Core). We like to know how to write the bootloader for M3-core and C-core. Either can you send us sample code or reference doc for to move further.

The application software code and the bootloader software code are the two different CCS projects, with different command files, and this two projects produce two OUT/HEX files.How to merge the Bootloader HEX file with Application HEX file, if you know any Hex file merger for TI and explain the process of merging the to hex file.

Hello

You can reference the C28 bootloaders of other devices such as F2806x in C2000Ware (under libraries/boot_rom). This flow will apply to C-core and M3-core. There should be minimal porting required to use on C-core.

Another option is to call the bootloaders in ROM from your application. Boot ROM symbols to do this are included in C2000Ware.

Regarding the two OUT/HEX files, refer :

HI Chris,

i don't know how to proceeding further with above example. Could you share only the m3-core bootloader code for better understanding to completing alteast m3 side.

Hello

When you generate the HEX via HEX utility, it should be in format to support the bootloader. In this case, you just call into the ROM bootloader from flash.

What bootloader are you interested in?

Best regards

Hi Chris,

we are looking for m3-core side right now and the details are below(perhaps me some details mayn't be correct also)

1. Bootloader project

-- It has separate .cmd file, it contains different memory region and memory allocation

-- Main.c file, jumping from bootloader location into application location

-- It gives hex/bin/out file to flash the target board

2. Application project

-- It has separate .cmd file, it contains different memory region and memory allocation, etc

-- Main.c file, Application code like LED blinking, PWM generation, printf functions and etc

-- It gives hex/bin/out file to flash the target board

Once i get the sample code for m3-core, it could help me to do the c28-core also.

Hello

Do you still need reference? You didn't accept my friend invite.

I'm going to close this post.

Best regards

Hi Chris,

sorry to reply after long time. yes i need support from you whether I2C, CAN, UART and SPI. Still i am not able to complete the m3 core bootloader to App jump mechanism.
