Hi community,

Our patner have tow questions about i.MX53 ENGcm10729.

Please the questions as below.

[Q1]
Please see WinCE BSP Status in IMX53CE Rev.5.
It says "Workaround implemented in WinCE BSP release APR2010.".
Would you let me know what codes are modified and how modify them?

[Q2]
It says " Customer software must avoid Device memory types." also.
Is this errata occurred by device driver or application software's code?
Or device driver or applicatoin software's code modification are not needed if windows OS care the workaroud?

Best Regards,
Satoshi Shimoda

Hi Satoshi,

Please check the ENGcm11413 device memory type can result in data abort. The Neon access to memory region marked as Strongly Ordered or Device are not usually a practical case in general Neon context is implemented in vfp source driver on BSP 1004.

Hope this helps
