Part Number: TMS320F28379D
Tool/software:
Greetins,
we are using it's TMS320F28379D board and everything is working fine. we are using TMS as hardware controller and from there we are sending some data using uart to hmi and from hmi we are getting data back (receiving) using uart communication, now the thing is what if:
to take the control card out and use it like this:
TMS320F28075PZPT
flashing and everything is working we have done pin connection also right but the only thing is when we tried to do communication using uart it is not happning.
I hava checked:
SCIB :
GPIO14_EPWM8A_SCITXDB_MCLKXB_OUTPUTXBAR3 -> RXB
GPIO15_EPWM8B_SCIRXDB_MFSXB_OUTPUTXBAR4 -> TXB
SCIA :
GPIO42_SDAA_SCITXDA_USB0DM -> TXA
GPIO43_SCLA_SCIRXDA_USB0DP -> RXA
USED CODE:
this code is working on the TMS320F28379D properly but on the TMS320F28075PZPT board, it is not working we have checked pin connections which is ok. but it is still not working, The code is flashing but data is not sending.
we use both pin connections and modify the code accordingly (SCIA & SCIB) on this working code, the current code is for SCIA.

}
For our expected output is there any modification that needs to be done, ether in code or on connections.
