Hello TI

This ticket is a continuation of
e2e.ti.com/.../tda4vl-q1-c7x-pc-mode-cgt-version-3-0-0-is-not-working

lo hi access is still not accessible in PC build. Below is the config

Version: TI_C7X_DSP_TRAINING_00.07
ti-cgt-c7000_3.0.0.STS (or) ti-cgt-c7000_3.1.0.LTS
xdctools_3_61_04_40_core
bios_6_83_02_07
Ubuntu 20.04 LTS
g++9

Atleast with ti-cgt-c7000_1.4.2.LTS, lo hi was accessible to a depth of level 2, but with ti-cgt-c7000_3.0.0.STS, even depth of level 1 is not accessible

Sample Code:

uchar64 temp1 = (uchar64)2;
uchar32 temp2 = temp1.lo;

Error:

conversion from ‘<unresolved overloaded function type>’ to non-scalar type ‘uchar32’ {aka ‘_c70_he_detail::vtype<unsigned char, 32, _c70_he_detail::VTYPE_KIND::DATA>’} requested
uchar32 temp2 = temp1.lo;

Hi Vigneshwar,

I have notified our C7x expert, but she is out until end of next week. Please expect delays in response.

Hi Vigneshwar,

Thank you for your patience while I am out. Can you see if the following snippet works (using .lo() instead of .lo ) on host emulation?

uchar64 temp1 = (uchar64)2;
uchar32 temp2 = temp1.lo();
uchar16 temp3 = temp1.lo().lo();
temp1.print();
temp2.print();
temp3.print();

Best,

Asha
