TMS320F28335PGFA Boot loader SCI won’t run after reset

Gregg,

Did you make sure you got the boot mode selection right? Please refer Table 2-2. Boot Mode Selection in TMS320x2833x, 2823x Boot ROM Reference Guide (Rev. A)

Since, you have already been successful in programming the flash right, you probably need to check whether you booting to flash correctly after you program the flash.

GPIO84,85,86,87 should be pulled high to "BOOT to flash". You should be in boot to flash mode when you trying execute the code out of flash

Manoj

Hi Manoj

We may have found the issue actually two problems looks like we had an issue with the top level code we were doing by 8 instead of 16. as it turns out our checking code was doing the same thing so it would checksum fine very strange. We should know tomorrow.

and yes we have the GPIO in the right mode everything works fine when downloaded from the Debug we may have just messed up the file.

Okay. Let us know how it goes.

My Problem seems to be the HEX2000.exe removes half my file it is intended for 8 bit systems I need 16 bit is there another converter already written for that.

Gregg

Seems to be all set we ended up writing a new converter to take care of the 16 bit issues now all is working. The only issue left is the same issue i have had with a 2808 when reset into Boot mode the serial port does not allways respond we get around that buy trying it multible times it evetualy works.

Thanks
