P2020 custom board booting from SDCARD

[kranthiyarragud]

Hi,

We are using P2020RDB design in our custom card where we are unable to boot from SDCARD.

Currently my processor ASLEEP=high, READY=low. kindly help us in debugging the booting issue, also let me know if you want me to monitor few other signal?

Regards,

Kranthi.

Please use a digital scope and check:

1) reset levels of all power-on reset configuraion pins to be in accordance with the projected ones.

2) reset levels of all pins having note 15 in the P2020 QorIQ Integrated Processor Hardware Specifications, Table 1. P2020 Pinout Listing.

Please consider creating a Technical Case and provide the processor connection schematics (as PDF) for inspection:
