TMS570LS1227: Programming spec for TMS570LS1227

Hi Jack,

Here is the flash library for programming and erasing the onchip flash:
www.ti.com/.../F021FLASHAPI

The "Advanced F021 Flash API Erase/Program Usage" and "reference guide" are also installed in the folder.

Hi QJ,

Thanks for your information.

Do you have the sample code or sample project for reference?

Thanks.

BR,

Jack Hsu

Hi QJ,

Thanks for your information.

Our engineer has completed the boot code through CCS, but he don't know how to read/write the boot code to ram of IC through DP programmer.

We used JTAG interface. Could you help to support it? or help to provide the document about boot code setup through JTAG.

In addition, we didn't find out the register define of ARM. Could you help to provide this document about this?

It is helpful to implement to set up programming process.

Thank you.

Hi Jack,

In CCS,
1. View --> Target configuation to create configuration file for your target
2. Launch the target configuration
3. Connect the device
4. RUN-->load the code to the flash

This is a good web to learn the target configuration, load code to the target.

Hi QJ,

Thanks for your information.

Maybe i didn't explain the situation clearly.

We are a programmer manufacturer(DediProg), and customer(Alpine) brought our programmer to program their ICs for production.

We need your help to develop this device into our programmer.

Now we have completed the boot code through CCS, and it works.

But we don't know how to write the boot loader into RAM of TMS570xx through our programmer with JTAG.

We need the detail information to embed the programming process into our programmer.   

There is our programming process.

Step 1. Power on and initialize (Maybe we need to know what's setting)

Step 2. Read JTAG ID and make sure the connection between programmer and IC.

Step 3. Load Boot code to RAM (we don't know the procedure and need your help)

Step 4. Set PC and run the boot loader

Step 5. Send the command to boot loader to do erase/program/verify

Step 6. finish

Thanks.

HiJack，

Does the step 3 mean the JTAG protocol?

In CCS, you can load the code to either flash or to the internal RAM. CCS has one menu called "scripts" which is used to swap flash and data RAM.

The main flash instruction memory is addressed starting at 0x00000000 by default. The CPU data RAM is addressed starting at 0x08000000 by default.

The device also supports the swapping of the CPU instruction memory (flash) and data memory (RAM). This can be done by configuring the MEM SWAP field of the Bus Matrix Module Control Register 1 (BMMCR1).

After swapping, the data RAM is accessed starting from 0x00000000 and the RAM ECC locations are accessed starting from 0x00400000. The flash memory is now accessed starting from 0x08000000.

Hi QJ,

Yes, we use JTAG interface for programming.

We know how to use CCS to load code to RAM, but it is used on the CCS.

We have to use our programmer to load boot code to RAM through JTAG, and control the boot code to do programming process.

Now our engineer use oscilloscope to capture the waveform and analysis the protocol, and then find the information from TI documents.

It is difficult to support this.

Could you share your email or Skype or Line or wechat? i want to connect our engineer to discuss this case with you directly.

Thank you.

Hello Jack,

Please add me as friend

Hi QJ,

Thanks for your support.

I show you the list which engineer captures the waveform and transform to data from TI tool with CCS.

I discuss this case with engineer.  Could you share the source code about download to ram and programming from CCS, or share some document as it. we think it is helpful for us.

In addition, Do you have engineer or FAE can help us in Taipei?

There is our email.

Thank you.
