Hi community,

 

I have a question about i.MX6 Android BSP (android_jb4.2.2_1.0.0).

A custom board of a customer does not boot rarely (about 3 / 2000 times).

Then, the customer investigated and found it was occurred when MMPF0100 returns NACK to I2C read access from i.MX6D on the timing between starting kernel uncompresssion and before mount rootfs of the boot sequence.

Actually, i.MX6D was stalled when NACK is returned, we think it is problem.

Then, please see our question as below.

 

 

[Q]

Is this i.MX6 stall issue by I2C NACK resolved with newer Android BSP (android_jb4.2.2_1.1.0)?

 

 

Best Regards,

Satoshi Shimoda
