Possible bug in uVision 2.31 (C51 7.01)

Hi all,
Could someone please check the following behaviour of uVision 2.31 (C51 7.01)?

If in the Options for Target... dialog you switch from the "Target" tab to the "Device" tab and then back to the "Target" tab, some of the options are lost.

For example, if the device is a SAB80C517A from Infineon, the "Use On-chip Arithmetic Unit" and "Use On-chip XRAM" check boxes are unchecked.

Thanks in advance,

Jose

  • Just switching between the tabs doesn't seem to do it.

    However, if I change the device - eg from Triscend TE502 to TE505 - that does cause the 'Use multiple DPTRs' and 'Use On-chip XRAM' options to be cleared (and maybe others - I didn't check).

    This is not a new behaviour: in previous versions, the Device & Target options were separate dialogues, but changing the Device had the same effect.
    I'm not sure that the behaviour is entirely unreasonable: changing the device is a pretty fundamental change, and could well invalidate some of the Target settings anyway! (eg, whether or not multiple DPTRs are available to be enabled!)
