BT  CODE

Hi Chi,

I will take a look.

VC  Example CODE

CAN   FAPI   FUNCTION   USER   GUIDE

Hello Wang
Thank you.
Thanks and Regards
QiuChi

I am still studying your code.

For PING command on PC side:
the data length is 0, you don't need to send 8 bytes data to bootloader.

Yes.However,If the data length is 0,the Tranmit function will return a fault value 0xffffffff. So I ask his factory.They say the data length can not sit 0.

Dear  QJ

It is my fault.The  DataLen  is 0  no problem. Now,I have corrected it in my code.

Thanks and Regards

Hi Qiuchi,

I read the code on PC side, they look ok to me.

Dear QJ Wang:

              So, what should I do next. I still think may be the problem appearing in the bootloader code that I transplant. I have posted my bootloader project in this theme.Do it can connect with my PC Code or other PC. Please give me some advice.May be I need rewrite

The Packetwrite() and Packetread()?In fact, I have some confused to figure out the code .

              Yesterday, I have load the APP by JTAG(start address is 10100).My bootloader can jump to the APP.

       Thanks and Regards

Sorry,QJ Wang,I am still bothered by this problem

Hi Qiuchi,

The CAN bootloader on MCU side works very well. After MCU boot, the boatloader keeps waiting for the command from your host side. If I were you, I would probe the CAN bus to check if the data on the CAN bus is correct. This is the CAN bootloader flowchart.

Dear QJ Wang;
In fact . I am familiar with this CAN Bootloader FlowChart.I find your code is switch and case sentence,its on problem. So I think the problem is Can driver code.

Thanks and Regards

My  modifications post below.

Dear QJ Wang:

              Thanks for your enthusiastic answer.

              Now, I have downloaded the code from e2e.By test, I found the CAN bus with data.

Step 1:I add the HW loak by HalCoGen generating code.

Step 2:Run the MCU  code and add the breakpoint at the sys_main.c.

Step 3:Run the PC Side  code and the program stopping at the breakpoint.

 Thanks and Regars

Dear QJ Wang:

Please give some advice for my next operation steps.

Thanks and Regards

Hi Chi,

Good job. What is the ID and data you got from PC? Are they consistent each other? In the sample code I gave you, the ID mask (DCAN IF1MSK) is cleared, this mean the ID is not used as acceptance filter. In the bootloader, ID is used to filter the coming message. This is why I want to know the ID and data. Thanks

Dear QJ  Wang:

Now,I test my PC code and post my data.

I send a PING and  a COMMAND Download order.

The Image_size is 74a0.   canID  changes from  0 to another value.

So,I do not sure what sector causes the problem.That is to say,canID=0x5A0  or  0x5A4 ?

In the bootloader, ID is used to filter the coming message?Sorry for it,according to my understand,ID=0x5Ax is right?

If I make a mistake to understand it?

In fact,My bootloader code is still your code. I am familiar with use HalCoGen so that I am too depending on it,even modify the 

bl_can.c.This is why I bothered by this problem so long time.Forgive my poor knowledge,Now I positively try to solve it.

Thanks and Regards

Qiuchi

 

Hi QiuCHi,

Your understanding is correct. The ID is 0x5Ax where "x" means "don't care".

The data looks good except for the ID. To get those data, do you use the sample code or use the bootloader?

Dear QJ Wang:

      I asked for leave a few days ago and I didn't reply to your post in time. I'm sorry.

     In fact .I didn't change the BT example some time ago, and I posted a post detailing the changes.

    But the program stays in the while statement.

 

Thanks and Regards

Qiuchi
