MCIMX6U7CVM08 BSDL

[hanshogendoorn]

According the BSDL file MCIMX6U7CVM08 is the boundary scan register length 648 bits, is this correct??

I am having a lot of problems when I am using this device in an interconnect test (Jtag Technologies soft/hardware).

Device id test is passing.

Kind regards, Hans

Hello,

Below are some general considerations.

1.

  Please check  if PCIe voltages are applied :

according to footnote of Table 2-21 (Recommended connections for unused

analog interfaces) of the Hardware Development Guide, linked below ,

SATA and PCIe supplies must remain powered if boundary scan test needs to be done.

< http://cache.freescale.com/files/32bit/doc/user_guide/IMX6DQ6SDLHDG.pdf >

2.

JTAG_MOD (SJC_MOD) should be pulled up (to NVCC_JTAG) for Boundary Scan Mode.

3.

Please check in BSDL file is correct for the i.MX6 part.

Please use the recent BSDL file from the Freescale Web :

“MX6DL_TO1.1.bsdl” file for i.MX6 DL.

https://cache.freescale.com/secured/NMG/MAD/IMX6_DL_S_BSDL.zip?__gda__=1447919960_27cec57af1ceb1395d...

Note :

“attribute BOUNDARY_LENGTH of MX6DL: entity is 648;”

4.

Please pay attention on COMPLIANCE_PATTERNS of the BSDL file.

attribute COMPLIANCE_PATTERNS of MX6S: entity is

  "(TEST_MODE, JTAG_MOD, POR_B) (011)";

Check if :

TEST_MODE is LOW ;

JTAG_MOD is HIGH ;

POR_B is HIGH.

Have a great day,
Yuri

Thanks Yuri,

I find out yesterday that the PCIE voltage is connected to GND , so I think I can stop debugging!

Only the device_id is read out correct.

Thanks, Hans
