Briey SDRAM Reverse Writing / Reading Error #195

Closed nvitya closed 3 years ago

nvitya commented 3 years ago

Hi,

Now I can debug the Briey SoC over JTAG! Tank you!

Clock Speed: 50 MHz Test board: QMTECH Cyclone IV Starter Kit (SDRAM = W9825G6JH6)

Unfortunatelly the SDRAM does not work properly like with QSYS, when tested backwards. It seems that the byte masking does not work somehow.

Here are the results of a 8-bit backward test with the Briey (2th Sep.):

END SDRAM Test

The 8-bit and 16-bit forward tests work error-free on both Briey and QSYS. The 32-bit backward test works error-free on both Briey and QSYS. The 16-bit backward test works error-free on on QSYS with DBusSimplePlugin.

Sorry my fault ! The DQM signal was commented out. Now the reverse testing also works with the Briey!. Thank you for your support.
