Part Number: TMS320F28P650DH
Other Parts Discussed in Thread: UNIFLASH

Hi Experts,

My customer is using F28P65 and F28003x with a JTAG daisy chain as described in the related question. They are able to connect to both device with CCS now, and is looking for a method for mass production.

They looked at uniflash. However, as they launch the uniflash session with a ccxml which have settings for the two DSP, and have been tested in CCS, they can only see the first device in the daisy chian, which is F28P650, and connot find the F28003x as the second device in the daisy chain.

We tried toggling the "bybass" option in the ccxml, but the uniflash can only find the first devices.

Is uniflash support device in daisy chain? what changes needs to be done to make it work?

PS: we currently have to ccxml tested in CCS, one can connects to the F28P650 and one can connects to the F28003x.

Regards,

Hang
