We managed to get it working. Summary: 1. It looks like calibration does not matter on power on. 2. Data extraction from SPI register should be taken care correctly. If 12 SCKs are used then it would be D0-D9. But if you use 16 SCKs the correct data would be D4-D13 as D0-D3 would be zero because there would be no data extraction.
