LS1012 boot

Hi,
on a custom LS1012 board we are facing this issue : clocks and resets ( both the PORESET_B and TRST_B ) come from the same source and are fine, RCW source ( CLK_OUT ) is open / pulled up to 1.8V , QSPI_A_CS0 and QSPI_A_DATA1 are pulled down to 0 to select the external oscillator, but we can't see any activity on QSPI to load RCW.
Powers are within the ranges, JTAG is enabled with TCK pulled high with a 4.7k to 1.8V.

Anybody has hints about this?
We have not yet tried with JTAG, can this be of some help?
Thanks and regards
