TMS320F2800155-Q1: flash drivers should be scolded to do it

By the way, the question I would like to ask is how do I take out the Flash drive separately?

Hi Zhang,

Could you explain your application a little more in detail and what TI tools/features you are trying to use?

Best Regards,

Delaney

Hi  Delaney，

Now I have a customer need，When I upgrade my software, I need to first write the FLASH driver function into my RAM, and then write to my application. Now my FLASH driver and my application are in a HEX, I need to separate them.But I don't have any idea now, can you give me some advice.

Best Regards,

Zhang

Hi Delaney,

The Flash driver is a hardware-dependent module that provides Flash erase and write functions for the ECU.
The Bootloader application software interlock mechanism, that is, the complete Flash driver code or its key parts are not in the Flash memory of the ECU
It is the RAM downloaded to the ECU during the reprogramming process. The Flash driver code must be removed from RAM at the end of the reprogramming.

Best Regards

Zhang

Hi Zhang,

I apologize for the delay; I have looped in the relevant expert, and they should have a response to you in the next day or so.

Best Regards,

Delaney

Hello Zhang,

Please take a look at one of the Flash kernel examples in C2000Ware (under directory driverlib\f280015x\examples\flash). We have two examples, one using SCI and one using CAN to program incoming data into the device Flash memory. You can adapt these examples for your use.

Hi Ibukun Olumuyiwa，

Thank you very much for taking time out of your busy schedule to answer my questions。

Here are some of the problems I encountered while debugging the program, and I would like to get some expert advice。

1、This is my cmd file configuration, there is a warning, how should I go to solve it

Warn for"../lib/source/280015x_generic_flash_lnk.cmd", line 69: warning #10334-D: No LOAD placement specified for initialized object "GROUP_1"; using RUN placement

2、When I use this CMD configuration file to run the program, it is easy to trigger an illegal interrupt. What is the cause of this

__interrupt void Interrupt_illegalOperationHandler(void)
{
//
// Something has gone wrong. The CPU has tried to execute an illegal
// instruction, generating an illegal instruction trap (ITRAP).
//
ESTOP0;
for(;;)
{
;
}
}

Hi Zhang,

The expert is currently out of office, so please expect a 1–2-day delay in response. Thank you.

This section should have a Load address associated with it. Please see this link for more information on linker cmd file configuration.
