palign(8) of .init_array messes up __TI_INITARRAY_Limit address |
Fixed |
PRU_2.2.0 |
PRU_2.2.0 |
In the linker command file, replace
.init_array > FLASH, palign(8), fill = 0xffffffff
with the following GROUP statement:
GROUP
{
.init_array
} > FLASH, palign(8)
The palign(8) on GROUP will ensure that any required padding is added after .init_array. However, both the size of .init_array and the value of __TI_INITARRAY_Limit remain unchanged. |
Applying palign(8) to .init_array caused __TI_INIT_ARRAY_Limit to be set to the end of .init_array including the padding. This broke RTS startup code responsible for calling constructors because the table of constructors now includes invalid data. This bug has been fixed and __TI_INIT_ARRAY_Limit is no longer affected by padding. |

PRU assembler rejects valid LBBO instruction |
Fixed |
PRU_2.2.0 |
PRU_2.2.0 |
Use formats of LBBO and SBBO instructions that specify immediate values in the 3rd or 4th operands. |
The PRU assembler rejected valid LBBO and SBBO instructions that specified registers for the 3rd and 4th operands, for example, LBBO &r3, r1, r2.w0, b0
The PRU assembler is now updated to accept this format for LBBO and SBBO instructions. |

Hex utility mishandles space in directory name of output file |

The hex utility did not correctly handle spaces in output directory and file names. |

Value of __cplusplus is wrong |
Fixed |
|
PRU_2.2.0 |
If possible, use the -ps or --strict_ansi options. This mode will use the strict definition of __cplusplus, which is 199711L. |
Our parser mimicked G++ behavior for the value of this macro in relaxed ANSI mode. This reproduced a bug in G++ versions v.4.7 and v.4.3 that has since been fixed. |

wrong workaround |
When using Ubuntu 16.04 and attempting to connect to a PRU core, CCS either freezes or collapses without a trace.
This was tested with both CCSv6.1.3 and CCSv6.2.0 on Ubuntu 16.04 64 bits and using XDS100v2 and XDS200 on AM335x devices. |
