| IDE-27850 | CoreSight ITM: trace table disappear suddenly | Trace - CoreSight Plugin | When the content of the trace data is changed, the user is asked to refresh the updated data. After the update, the trace data editor is closed. The user needs to open the editor again to see the updated trace data. |
| IDE-23041 | Missing support in startup code for CCRX to GCC converter | CCRX to GCC Converter | The CCRX to GCC converrsion tool does not perform a 100% guaranteed conversion. Here are some problems that may require further manual correction. Missing explicit setting of usp and isp registers. In resetprg.c, function PowerON_Reset_PC() there is no explicit call to set_isp() or set_usp(). While ccrx compiler automatically adds asm code to setup isp and usp registers, once converted to gcc, there is no translation for the missing code. At the start of gcc function PowerON_Reset_PC() please add the following code: __builtin_rx_mvtc (0xA, sstack); __builtin_rx_mvtc (0x2, ustack); Initialization of variables is not ported. Functions _INITSCT, _CALL_INIT and _CALL_END all play a crucial role for initializing global variables, and objects. However, ccrx compiler exposes these functions only as ccrx libraries. _SECTOP_EVECT is missing, for rxv2 architecture exception table and may be different then interrupt vector table. Incomplete translation in PowerON_Reset_PC() The code "set_extb(__sectop("EXCEPTVECT"));" should be "__builtin_rx_mvtc (0xD, __SECTOP_EVECT);" |
