TE0720-04 QSPI boot not working

Hi,
my boot.bin works fine via JTAG, but it is impossible to boot from QSPI on the TE0720-04 (on the TE0720-03 works the same boot.bin fine via QSPI).
We have the MODE pin floating, but I have tried keep to GND or 3V3, but no success.
The Vivado (2019.1) HW manager shows:
TE0720-04
- when boot MODE pin is high(floating) - The current boot mode is SD
- when boot MODE pin is low - The current boot mode is JTAG

TE0720-03
- when boot MODE pin is high(floating) - The current boot mode is QSPI
- when boot MODE pin is low - The current boot mode is SD

How can I get boot mode to QSPI on TE0720-04?

Thanks
Ondrej

Hi,

how did you use PGOOD Pin? With newest CPLD Firmware we add the option to use PGOOD Pin also as additional Mode pin(bidirectional pin, input used for boot mode and output for Power Monitoring). In case PGOOD Pin is drive low by carrier boot mode is changed to JTAG only, to program QSPI with newer version of VIVADO tools.

But in your case it sounds strange, because you say Mode Pin high is SD card, this should be QSPI as long as PGOOD pin is high. Do you have the original CPLD Firmware on the module? Or is it a typo? You mean high JTAG and low SD for TE0720-04?
