LS1017 ioconfig/TDR-Register

[RS_PW]

I'm looking for the description of the TDR-Register of the LS1017 (LS1028). I have to make an Boundary-Scan test for the Rams connected to the LS1017 (the chain and some other tests are working), I'm using Goepel. How have I to set uo the TDR-Register to make it work? I didn't find an application-note for this.
I found this (https://community.nxp.com/t5/Layerscape/LS1027-LS1028-BoundaryScan/m-p/1598849#M11855), but it didn't help me.
Thanks in advance
Rolf

Please try with following TDR value 0x00080000003fc6c512ae6240000000000000000026ffd00000000000000055555555155550005000015540000005294a52aac40d0000

unfortunately it's not working
Here is my sequence:

LDI CPU_873, IOCONFIG;
IRSHIFT;
CPU_873: TDR:= 00080000003fc6c512ae6240000000000000000026ffd00000000000000055555555155550005000015540000005294a52aac40d0000H;
DRSHIFT;

CLOCK RUNIDLE, 2000;

It's the same result like before

TDR is test data register and it is available in BSDL file. Opcode/instructions are also mention in BSDL file. TDR register is used to comply with IEEE1149.6 specifications and are prat of JTAG specification. Implementation of this register is SoC specific.

1. For BSDL operation to be successful, USB power pins (USB_SVDD, USB_SDVDD and USB_HVDD) should be powered.
2. LS1028A's BSDL refers to the register "TDR_INITDATA[430]" and corresponding instructions INIT_SETUP, INIT_RUN. Customer needs to set TDR_INITDATA register with "0x000016046aa94a529400000055500001400155551555555540000000000000017fec80000000000000000048cea9146c7f8000000200" value.
3. Once TDR_INITDATA data register is set then customer needs to feed ~2000TCLK so that BSR chain get complete. Once chain is complete than whatever is feed from TDI will be received at the TDO.
