Booting with Custom Board

Started by shad...@yahoo.com June 23, 2008
Hi, all.

I'm designing the custom board using TMS320C6416T DSP.

I want to run the program on the custom board with JTAG emulator and CCS.

Is it possible to do this with 'No boot' Mode?

My design includes no flash rom, HPI or PCI.

Yes, but... The meaning of 'No Boot Mode' is to start executing the code at
address 0. This will try to execute whatever 'bits are there'. This can
sometimes get the target in a confused state [from executing illegal
opcodes] and prevent connection with an emulator.

I suggest designing the board to be configured for HPI boot - even if you
have no HPI. This will cause the DSP to come up waiting for HPI input [and
DSP_INT] and no code will be executed. When the emulator comes up and times
out [you will not see this] trying to connect, it will assume that the
device might be in HPI boot mode, issue a DSP_INT and 'take control' of the
device.

BTW, are you aware that a board like this can only be used with CCS??
