[FAQ] TMS320C6657: How to flash the IBL ( Intermediate Boot loader ) into EEPROM and how to flash the application binary into NOR? How to boot the IBL + Application binary?

How to flash the IBL ( Intermediate Boot loader ) into EEPROM and how to flash the application binary into NOR?

How to boot the IBL + Application binary? on C6657 EVM using CCS 9.3

Pre-requisite 

1. Install processor_sdk_rtos_c665x_6_03_00_106 from http://software-dl.ti.com/processor-sdk-rtos/esd/C665x/latest/index_FDS.html
2. Install CCS 9.3 from CCSTUDIO_9.3.0.00012 | TI.com
3. Choose the installation directory as C:\ti

Step1: -- Building IBL

1. Build the IBL by following these links :- 

     To build IBL in Windows-10 - [FAQ] PROCESSOR-SDK-C665X: IBL Build Steps on Windows 10 (Processor family: C665x) - Processors forum - Processors - TI E2E support forums

     To build IBL in Linux- [FAQ] PROCESSOR-SDK-C665X: IBL Build Steps on Linux (Ubuntu) (Processor family: C665x) - Processors forum - Processors - TI E2E support forums

2. After building the IBL, "i2crom_0x51_c6657_le.bin", IBL-binary will be generated at C:\ti\pdk_c665x_2_0_16\packages\ti\boot\ibl\src\make\bin

Step2: -- Flashing IBL

a. Set the DIP switch into "NO-BOOT" mode. "SW3 and SW5"

b. Modify the eepromwriter_input.txt located at "C:\ti\pdk_c665x_2_0_16\packages\ti\boot\writer\eeprom\evmc6657l\bin"

file_name = i2crom.bin
bus_addr = 0x51
start_addr = 0
swap_data = 0

c. Flashing steps as follows ( Flashing IBL into EEPROM using EEPROM writer)

1. Set your C66657EVM to NO BOOT. Power on, launch target configuration in CCS, and connect to Core 0. Be sure the GEL file is used and DDR is initialized.
2. Copy the IBLbinary you want to flash to "C:\ti\pdk_c665x_2_0_16\packages\ti\boot\writer\eeprom\evmc6657l\bin" directory.
3. Rename the binary you copied in the previous step to “i2crom.bin”.
4. In CCS, select Core 0 and open the Memory Browser. In the Memory Browser window, right click and select “Load Memory”
5. Load your "i2crom.bin" to 0x0C000000. Do so by selecting i2crom.bin file and select the file type as binary. click Next, and input 0x0C000000 as Start Address
6. Load C:\ti\pdk_c665x_2_0_16\packages\ti\boot\writer\eeprom\evmc6657l\bin\eepromwriter_evm6657l.out
7. Run Core 0. This will program the flash memory.

If it succeeds, the console will print “EEPROM programming completed successfully”

Step 3 -  Booting IBL:

1. Change the DIP switch settings into

1. Open hyper terminal or putty and Connect the UART
2. Observe the IBL booting with version either as 1.0.0.15 or 1.0.017
3. 

Step 4 - Flashing app

1. The sample binary taken for this demonstration is UART_BasicExample_C6657_c66xTestProject.

2. Located at C:\ti\pdk_c665x_2_0_16\packages\MyExampleProjects\UART_BasicExample_C6657_c66xTestProject

3. Build and create the app binary using CCS 9.3

4. App binary, UART_BasicExample_C6657_c66xTestProject.out will be located at  "C:\ti\pdk_c665x_2_0_16\packages\MyExampleProjects\UART_BasicExample_C6657_c66xTestProject\Debug\"

5. Flashing app binary into NOR-memory using NOR-writer.

1. Set your EVM to NO BOOT. Power on, launch target configuration in CCS, and connect to Core 0. Be sure the GEL file is used and DDR is initialized.
2. Copy the UART-app binary you want to flash to "C:\ti\pdk_c665x_2_0_16\packages\ti\boot\writer\nor\evmc6657l\bin" directory.
3. Rename the binary you copied in the previous step to “app.bin”.
4. In CCS, select Core 0 and open the Memory Browser
5. In the Memory Browser window, right click and select “Load Memory”
6. Load your app.bin to 0x80000000. Do so by selecting app.bin for the file, click Next, and input 0x80000000 for Start Address (Type-size selected should be 32-bit)
7. Load C:\ti\pdk_c665x_2_0_16\packages\ti\boot\writer\nor\evmc6657l\bin\norwriter_evm6657l.out
8. Run Core 0. This will program the flash memory.

If it succeeds, the console will print “NOR programming completed successfully”

Step 5 - Booting IBL + app binary

1. Change the DIP switch settings into

1. Open hyper terminal or putty and Connect the UART
2. Observe the IBL booting with version, 1.0.0.15 or 1.0.017
3. Observe the IBL jumps to the UART app.
