Updating MOD-SDR-DAC32B (P16336 ONLY) (TN579)

As the number of 32-bit DAC cards in the market has increased, we have found that due to minor part tolerances there are a small number of the latest 32-bit DAC cards, with Zynq firmware chip (P16336), which can very intermittently fail to boot correctly. This manifests as the slot showing as empty in the Audio I/O window. As this is not wide-spread, we suggest only to update to firmware version 35 for cards that may intermittently fail to initialise.

 

V35 is an update to the previously released v33 firmware and provides an initialization specifically targeted at these edge cases. There is no requirement to upgrade all cards in your inventory. Cards which initialise reliably with the v33 firmware can remain on v33 firmware.

Earlier 32-bit DAC cards (P16239 variant) do not require any firmware upgrade.
