Can you please upgrade your atf/mv_ddr to the newest versions:<br>
<a href="https://github.com/MarvellEmbeddedProcessors/atf-marvell/commits/atf-v1.3-armada-17.06">https://github.com/MarvellEmbeddedProcessors/atf-marvell/commits/atf-v1.3-armada-17.06</a><br>
<a href="https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell/commits/mv_ddr-armada-17.06">https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell/commits/mv_ddr-armada-17.06</a><br>
<br>
Also, although it should be less relevant here, you can use the newest u-boot<br>
<a href="https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commits/u-boot-2017.03-armada-17.06">https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/commits/u-boot-2017.03-armada-17.06</a><br>
<br>
Please let know if you observe any improvement.<br>
<br>
Best regards,<br>
Marcin<br>
