Hi,
I have been stuck on this problem for a couple of days now. I am trying to flash the timed_led_blink example from TI through SCI to my F28069M on a custom board. I have made shure and controlled that when I boot the chip it is in SCI boot mode. After sending the hex numbers 0x41 followed by 0xAA and 0X08 I try to flash the programm to my chip with the command prompt. I do this by using the standard line given in the 3652.Serial Flash Programming PDF of TI: :> .\serial_flash_programmer.exe –d f2806x –k ~\Debug\f28069_sci_flash_kernel.txt -a ~\Debug\Example_2806xLEDBlink.txt -p COM6 -b 9600 -v.
After doing this I get the following result:
So what I have done to see where the problem is is editing the sci_flash_programmer given by TI by adding some VERBOSEPRINT's, I have done this to see in which part the problem lays.
I have added the comments in the f05_DownloadImage.cpp file:
After doing this the output was as following:
With this output I found out that the problem lays at the if statement at line 219 where it checks the checksum.
I have gone through dozens of forums and checked every possible problem such as; making shure the sci-pins are good in the kernel and kernel hex file, making shure my memory ranges are correct. But after all this searching and digging I am still stuck so I need your guys help.
I am using the F28069M on a custom made board, to communicate between my laptop and the PCB I am using a CP210x USB to UART cable. The board is powered by a power supply with 36V and 0.5A (this is the recuired power).
Additional information: Flashing the timed_led_blink example with the XDS110 debug probe works perfectly, flashing any other program with this tool works fine as well. The only change made in the timed_led_blink project is the change of the GPIO pin 34 to GPIO12 since this is LED1 on my board. I have made shure to also change the MUX and DIR so it works all fine(tested with debug probe).
I'm lokking forward hearing your advise,
Greetings Guilliam
