TMS570LS3137: tms570LS3137hdk and TMS570LS3137PGE

Part Number: TMS570LS3137
Other Parts Discussed in Thread: HALCOGEN

hello 

my code which  generate in HCG  TMS570LS3137PGE.it  works well  in TMS570LS3137HDK about LINRX with  LINRX interrupt mode .but it not has response  in TMS570LS3137PGE ,it has the signal in the chip pin(PGE131LINRX),but it can not receive anything.it can send data with LINTX use  TMS570LS3137PGE board ,which is our team made by ourselves.can you give me some advise

    Hello User,

    There is no difference between LINRX on the ZWT package as used in the HDK vs the LINRX in the PGE package. Did you regenerate the code using a new Halcogen project for the PGE package or did your original code use the PGE selection from Halcogen on the HDK? Perhaps there is something blocking if you are using Halcogen generated code that was setup as ZWT for the HDK. I can't immediately think of anything that would impact like this, but it is worth checking if you have already compared schematics between the HDK and your custom board. HDK schematics are available at this link: processors.wiki.ti.com/.../TMS570LS31x_HDK_Kit

    my code generate in TMS570LS3137PGE project,it can work in HDK board(TMS570LS3137ZWT)whatever send or receive, and my board LIN is as follows,it can send but not receive

    Hello User,

    Have you checked the output at the RO pin? Also, I don't see any inline resistors between the MAXIM part and the MCU? Do you have these as the HDK has them? Also please check the voltage levels on the RO pin and for the MAXIM supply in general since the output voltage is dependent on it.

    Also, I assume the SW was working with this same transceiver connected to the HDK per your original statement that it was working with the HDK but not now with your custom board?

    thanks for your reply ,i have solved ,because my moxa RS422 transmiter is broken ,so i can not receive the data,thans again
