I am getting the "Flash not Erased" error when writing to NOR flash with cp.b. I checked all of the obvious such as file exceeding the erased area etc.

Below is the log including environment settings etc. You can see that about 14k of data is written and then the error occurs for a reason unbeknownst to me. Any suggestions are appreciated.

Now, you may want to say "try a newer version of u-boot". However, that is not feasible due to other requirements. However, if there has been a known issue that has been fixed later, please let me know, what it is so that I can eventually backport it. I could not find it while searching the web and the mailing list posts.

Thank you, Rudi
