Hello experts,
We are facing what it seems to be a firmware bug on the CC2564.
It occurs this problem while keeping the multi connections(6 - 10 connections) for BLE and performing LE scan.
Then TI logger shows errors:
157956520 03:06:45.111 +0:01:06.450 ERROR: Data Abort !!!, Link Register: 0xe10f0004
157956521 03:06:45.111 +0:01:06.450 ERROR: Data Abort !!!, Link Register: 0xe10f0004
157956522 03:06:45.112 +0:01:06.451 ERROR: Data Abort !!!, Link Register: 0xe10f0004
157956523 03:06:45.112 +0:01:06.451 ERROR: Data Abort !!!, Link Register: 0xe10f0004
Beyound this point, the chip does not answer to HCI commands. This is reproductible on many of our boards embedding the CC2564 and may occur after half days of continous normal operation.
Then we seem this problem is recovered by chip reset only. We cannot tolerate this recovery method.
Our boards use:
OS : Linux 3.10
BTS file: initscripts-TIInit_6.7.16_bt_spec_4.1.bts/initscripts-TIInit_6.7.16_ble_add-on.bts
Please find the attached log cc2564b_hangup_issue.zip.zip
Any help on this matter would be highly appreciated,
Best regards,
