4.1 Issue 1 - Embedded XDS110 Connection to AM64x Target in CCS
Applicable EVM Revisions
: E2
Issue Description
: On some EVM, the embedded XDS110 (U59) has been shown to fail initial target connection
to AM64x target in CCS after first EVM and XDS110 power cycle. No problem exists when using an attached,
external emulator over the CTI20 header (J25).
This failure mode can be encountered by following the steps below:
1. XDS110 USB is attached between host PC and XDS110 USB port (J28).
2. EVM power is enabled and the AM64x is brought up in
no-boot
mode.
3. In CCS, an initial CCS target connection to the M3 DMSC core is then attempted.
