Hi trying to load a boot and APP image via JTAG to SoC (AM6548) to QSPI

I need to understand how can I load the Image to QSPI (for boot and app) for the first time ...

Can someone please guide me in the right direction?

I know the TI EVM has OSPI and the previous post is stating that TI will develop a driver for QSPI - any status?

Linux OS, SDK 06.00.00.07

Please advise!

Please clarify if the AM65x is running Linux or RTOS?

I am asking what OS you are running on the AM65x, not on your Host PC.

Thank you for your efforts!

Hello,

Is it possible for you to boot from a SD card and program the QSPI using the OSPI instructions mentioned in the following document? Also please refer to the file <u_boot>/drivers/mtd/spi/spi-nor-ids.c file to see the list of supported Flash IDs and make sure the CONFIG option for your flash device is enabled.

Regards,
Krunal

For the EVM we can do SD card boot but it will not help us because the Custom H/W platform does not support SD boot.

I was guided to this material by TI field ENG

http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#programming-flashwriter-on-am65xx-platform

section 3.5.1.7

If you have feed back about this procedure, please do share !

So i have a issues with the Flash Writer instructions.

Launch and setup CCS for AM65xx to configure DDR and load the DMSC firmware. Refer below link for detailed instructions http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/How_to_Guides.html#ccs-host-setup
Connect the USB cable between USB2UART port (J42) of the board and host PC
Configure the board to “no boot” mode
Configure the serial console application on host PC to connect to MAIN UART0 port. Connect to the first COM port out of four COM ports detected.
Launch target config file for AM65xx platform and connect to A53 core.
Load the flash writer binary <path_to_the_uniflash>/processors/FlashWriter/am65xx_evm/uart_am65xx_evm_flash_programmer.out to A53 core.
Run the program and confirm that character ‘C’ is getting printed on the host PC serial console. Make a note of the COM port number.

I don't get the C output !

I have tried all ports, I assume the baud rate is 115200 !

I do not get any errors either !

Please advise!

Hi All,

To resolve Florin's issue, we had to use Uniflash version 4.5, no other version of Uniflash we tried worked, and even then we could only successfully load a program using a Windows machine, with Ubuntu failing to complete the dslite command.

I will start a new thread regarding the new issues.

Thanks,
Barend

UPDATE:

So I have tried uniflash 5.1 and it didn't work!

But I tried uniflash version 4.5 and it did (4.6 doesn't work either)

Now I am getting the C output on the serial terminal.

Doing the Erase flash command:

For Linux

# cd <path_to_the_uniflash>
# sudo ./dslite.sh --mode processors -c <COM_Port> -e <Erase_Length_in_bytes> -d <device_type> -o <Erase_Offset>
Example:
# sudo ./dslite.sh  --mode processors -c /dev/ttyUSB1 -e 10000 -d 1 -o 20000

Nothing happens and it gets stuck @ "Transfering Header information.." 

Coworkers using windows platforms were able to complete the process... Exactly the same procedure and steps- commands are different ...
So why doe it not work on a linux Ubuntu 18.04 platform ...?
Please advise!
