I have a Controller(TMS320F28379D) and EEPROM(25AA512, spi interface), i was trying to boot this controller with EEPROM in boot mode so that the controller takes the code from EEPROM. can you guide me with the appropriate steps. I have referred the reference manual of the controller section 4.10.4.3 SPI Boot Mode, but the information is not clear.
NOTE : not looking for EEPROM emulation using flash

1. Open CCS, view and launch the target configuration file
=> what to do after launching the target configuration file ?
2. In the debug window, right click CPU1 and connect to target
3. Under the view tab, click the memory browser window and input address 0xD00. At this address, type the hex value 0x8104.
=> Done successfully
4. In the toolbar pane, click the CPU Reset button for CPU1 and then press the resume button.
Now after clicking cpu reset following occurs :
after clicking resume following occurs:
I can't see how this is getting me into spi boot mode ?
Question1) In TRM of TMS320F28x controller, in spi boot mode section 4.10.4.3, can you tell me the steps 1 to 8 are to be coded inside the main function, or before the main function,
a) if inside the main function then where, just after start of main function or where?
b) if before the main function then where?
Question2) And in this steps of section 4.10.4.3 or in TRM, it is not clear how the code/controller is determining which code it should be running, whether from EEPROM or flash\
Question3) which are the boot pins for spi boot mode : 
a) It is not clear gpio pins for spi mode, please clear this
b) And where is the BOOTCTRL register in code, and how to configure it if required
Question4) can you please provide an example code, because in TRM it is really not clear, how to achieve the task(task : i want to program hex file from external eeprom into the controller, because onsite we don't want to program the controller so we want to put the hex file in external eeprom and simply plug into the pcb and reset the board while adding the jumper pin to boot pins, so the controller should get the updated hex file from eeprom)
Hi Allison,
Still waiting for your reply.
I want to share some steps i have have done and have some questions regarding the same,
Note: There are two projects of led blinking, a) 300ms led blinking for eeprom b) 100ms led blinking for controller
A) Dumping hex file in external eeprom
=> 300ms led blinking code (hex file) to be dump inside external eeprom
=> Before dumping i have set some settings in properties-> C2000 Hex Utility-> Boot Table Options -> set a) Select boot mode, b) SPI-A port, 8-bit mode(--spi8, -spi8)
=> Output format Options -> set 'Intel hex'
=> Building the project
=> When reading this hex file, i can see the key = 0x8AA in first two bytes
B) Standalone Boot
=> Debug Configurations-> Target-> Flash Settings-> Z1-Bootctrl(0x7801e) = 0x0000045A
=> After building -> debug mode
as you can see the value of z1-bootctrl in memory browser
=> CPU Reset
=> Resume
=> Pause
as you can see the value of bootctrl register is not changed, and the controller code is running instead of eeprom code
=> You can see Boot Status Registers as well, as there is flash boot in the register value, instead of spi boot
=> I Think the controller is not getting into spi boot, because the address i am setting the value (0x045A) is not wrong address you provided in TRM, because as you can see in memory browser below the address is 0x0005F004 instead of 0x7801e, and if 0x0005F004 is the correcet address for setting the bootctrl register then please tell me how to do it, because in flash settings of target in debug configurations the address is 0x7801e
=> And one more thing do i have to set the other register as well in flash setting, refer below picture
NOTE: I done power reset my controller board in standalone boot as well, but controller code is running instead of eeprom code
B) Emulation Mode
=> Setted the value 0x045A in register 0x00d00 in debug mode
=> CPU Reset
=> Resume
=> Pause
=> Even in emulation mode controller code is running instead of eeprom code
I am waiting for your reply as soon as possible, am still asking for a example code or any documentation from you.
Best Regards
Saddam
Hi Saddam,
It looks like when you resume and the re-pause your program from the screenshots above, this is passed where SPI_Boot.c is actually referenced.
Below are some instructions to step through the Emulation SPI Boot process give more context as to where SPI_Boot.c is called. This can help to check that you are seeing SPI communication successfully as well.
), and click 'Load Symbols'Please let me know if you are able to follow these steps and see SPI communication.
WARNING: You can only program the OTP boot control key twice, so be sure to verify that everything works in emulation mode before actually programming OTP. You can program the key into OTP using 'Tools' > 'On-Chip Flash'. Scroll down to 'OTPBOOTCTRL' and type it there before pressing the button to program it. But, again, proceed with caution here:

Allison
Hi Allison,
All the steps you mentioned works perfectly fine, and yes i am able to establish the SPI communication between external eeprom and controller, because in SPI_start_Boot() i can see it is reading the key : 0x08AA, which means spi is working and returning the entryAddress(Decimal :545171).
But when i run resume after getting the entry address, it doesn't run the eeprom code, it still runs the controller code.
Screenshots for your reference are as follows:
1)After completing the spi_boot() function which returns entryAddress, and i am going step by step till the exitBoot, and pressing resume, then code goes nowwhere(refer pic 4)):

Hi Skyler,
1) You can see in the screenshot, the address is 0x00085193, this occured when i followed allison steps
2)It should be intel hex(i think), because when i read the ASCII hex file i don't see the key (0x08AA) on first two bytes and later on, but i can see the key and other things like baudrate in intel hex file.
ASCII Hex file
Intel Hex file
3) You can see in the screen shot in my above response, In Debug Mode i can see my code running that is led blinking, but when i pause the program then that nowwhere thing appears(refer the screenshot in previous response Pic 4).

Hi Allison,
I am generating the output files, by setting the output format in properties->c2000 Hex Utility-> Output Format Options and building the project, then the hex file is generated.
1) can you tell whether what should be the 'EntryAddress' after the spi_boot is completed, which is at the boot exit.
2) you want me to do this step after the boot is completed, i.e when the code is at boot exit or at the cpu reset?
so when you pause it, try loading the .out file of your project's code.
3) i think the loading of symbols is correct, that is the reason the code is running the spi boot functions, and if not then please tell me how to do it in correct way.
4) i was not able to send you the .cmd file, hence i have provided the screenshot of the content of the file.

Hi Skyler,
first let me clear that there are two codes : one for eeprom(led blink 300ms) and other for controller(led blink 1s).
1) I have programmed the controller via controller code and set in debug mode, then done cpu reset and then loaded symbols : "C:\ti\c2000\C2000Ware_2_01_00_00\libraries\boot_rom\f2837xd\revB\rom_sources\ccs_files\cpu01\Release\F2837x_cpu01_bootROM_REVB_Golden_020314.out", and done further steps as guided from Allison in above messages.
2)
To load the symbols, pause the debug session after the LED application has successfully been loaded, navigate to "Load Symbols", and select the .out file corresponding to the LED Blinky application project
I didn't get by what you mean in this quoted message, do you want me to load the .out file of eeprom code or controller code?
3)
Best Regards
Saddam
