TMS570LS1114: Bootloader can not work well?The way to verify write successfully?

Qiu chi

Dear Experts:

I am working on TMS570LS11x && TMS570LS12x Bootloader .Now I make sure the PC Side Code work well and I transplant the code in my own Hyper Terminal which is designed based on VS2010. I still have some questions to verify my Bootloader function.

My device is TMS570LS1114 for example and the hardware platform is my own board which designed by ourselves.

Now I have correctly generated a file whose form is Prj_DCAN_Test.bin. But why I find My PC cast lots of time more than 60 secends to load data? I find the Image(APP bin file) only 29K.

In fact, My program is still stop in the same position.

Can I add a breakpoint after the next instruction to verify my bootloader receiving the data?

Now I will display the main modify section to you,Please give me some advice to solve the interface problem.

The Code is

#1 bl_config.h

#define CAN_BIT 500000 /*can be 125K, 250K, 500K, 750K, 1000K. The default is 125K*/

#define SYS_CLK_FREQ 160 //MHz

#2 flash_defines.h

#define TMS570LS11

#3 bl_dcan.c

g_ulForced =1 ;

Due to my hardware platform which is lack of a test pin PORTA 7 ,So I forcedly

Updaata by change the flag valve.

After operate the above steps.I see the Memory Broser 0x00010000 ,and I find no data?

Whether I invalidly operate ?

Best and Regards

Hello Qiuchi,

Your PC side code doesn't transmit CAN message package properly.
1. Open you binary file, read the file to a buffer
2. Configure the CAN interface with your USB-CAN adapter, and open the CAN network interface object (RX and TX). Make sure this initialization is successful (the APIs should return status)
3. Send a CAN message to ping MCU: The mesasge ID is CAN_COMMAND_PING. If ping fails, the CAN interface is not configured correctly.

How many CAN channels and CAN transceivers are on your PCB board? If you have 2 CAN transceivers on your board, you can use those 2 CANs to test your code.

Dear QJ Wang:

#1 I make sure the first point no problem.

The following is the Prj_DCAN_TEST.bin file

The Buffer valve as the follow:

#2 My Hyper Terminal can reicieve data in other app,should I add the code to test in bootloader APP to test?

In fact ,Your sample code I only modify I post .So if still problems in the bootloader code or PC Side Code?

Now,I will test the interface problem fixed on Hyper Trminal.And I still have confused to send a message ID is CAN_COMMAND_PING.Because I transplant the code a key load.

Dear QJ Wang

I add two breakpoint to test

The first breakpoint, dwRel=0xffffffff;The second breakpoint,dwRel=0x00000018

Hello,

What is the return value of Transmit(..) and Receive(..) if the the message is transmitted or received successfully? I think the value (0xFFFFFFFF, and OX018) you got is not correct.

Yes,I find a Bug .Transmit (...)and Receive (...) use the same buffer,Now I try to modify

Dear QJ Wang
There are several varable I think it is not correct. rcvID, rcvData.Transmit (...)and Receive (...) may still have problem.
I still debug.
Thank your advice.
