I have 50 pcb-s where I can't read device and manufacture ID
component soldered, ABA analysis carried out, error goes with component
What could be the reason?
Another batch of components works without problems.
#DEFINE READ_ID WD=0x9F RD=MAN_ID RD=DEV_ID CE_HI
#MAN_ID=0x34
#DEV_ID=0x2A
pass
*** No precondition file present ****
**** Manufacturer ID matches ****
Found: 0x34, Expected: 0x34
**** Device ID matches ****
Found: 0x2A, Expected: 0x2A
fail
**** Manufacturer ID ****
Scan path malfunction
**** Device ID Error ****
Found: 0x0, Expected: 0x2A
Solved! Go to Solution.

Hello,
Can you please check with the customer on below questions:
- Do these problematic devices have the same OPN as the working ones?
- Did the customer test a problematic component on a known good board?
- Can they test with sending 0x9F command at both 1-1-1 mode and 4-4-4 mode?
- What is the clock frequency 0x9F command running at?
- Can they read out the CFR3V register value from both good and problematic devices and send to us?
Thank you
Regards,
Bushra
