Other Parts Discussed in Thread: AM2634, SYSCONFIG
Tool/software:
TI AM2634 has failed to initialize UART in SBL.
After debugging, it is found that it is always stuck in SBL, and the UART initialization processing of the following TI generation code. Disconnecting the power supply and reconnecting it, this problem still exists.
Please confirm what caused this problem.
Confirmed points:
1. The QSPI Clock waveform is OK,when PBL load the SBL at startup.
2. The SBL data read from the external FLASH is the same as the primary data .
3. The same problem will happen when SBL is downloaded to SRAM for execution by using debug mode.
4. In debug, the values of SYSC and SYSS registers are both 0.
