How can we help you today?
Where can I find M241 M251 firmwares with version < v4.0.6.38 ?
Firmwares with version >= v4.0.6.38 include a major optimization on DDR (RAM memory of controller) timing.

If necessary older versions can be obtained from technical support, but it is highly recommended to use version >= v4.0.6.38.
