Hi, I am looking for additional details on Errata ERR050577. I am working on the RT1052. If I follow the recommendation of the Errata, the burst length is configured as 1 and there will be significant SDRAM performance reduction.
Is there a different workaround for this Errata that allows burst length > 1? What if SDRAM3[UT] (Refresh urgent threshold) and/or STDRAM[RT] (Refresh timer period) values are reduced?
Thanks in advance.
Unfortunately, there are no specific regulations to avoid this errata. The only requirement to avoid the errata effect is to set the burst length to 1.
Is there a way to determine whether the error condition can occur? Or common problem cases? For example, large DMA transfers?
