Part Number: AM6442
Hi Experts:
Our customer meet long time run linux kernel panic issue at AM64x board. Some board run ~50 hours or several days it will happen kernel panic. Now customer are doint ABBA swap test, isolation it relathionship with LPDDR4 or AM64x device.
Because this problem is difficult reproduct, we can not do many board ABBA swap. So customer want to check whether AM64x LPDDR4 controller support like DDR5's loopback mode. If AM64x LPDDR4 controller support loopback mode, we can use many failure board run the loopback test, to insure the data abort happen at external LPDDR4 or AM64x internal DDR controller.
Could you please share those information and if support LPDDR4 loopback, please share the enable method.
Best Regards!
Han Tao
