Try it like
#include <stdint.h>

extern  uint64_t lwdata[];

void target_data4_req(uint8_t *canFrame_Tx, uint8_t index)
{

    canFrame_Tx[0] = lwdata[0] & 0xff;
    canFrame_Tx[1] = lwdata[0] >>   8;
    canFrame_Tx[2] = lwdata[0] >>  16;
    canFrame_Tx[3] = lwdata[0] >>  24;
    canFrame_Tx[4] = lwdata[0] >>  32;
    canFrame_Tx[5] = lwdata[0] >>  40;
    canFrame_Tx[6] = lwdata[0] >>  48;
    canFrame_Tx[7] = lwdata[0] >>  56;

}

and look yourself...
