In write_vmem() in fb_ssd1306.c file, changed as
set the txbuf.buf to 0xFF before the below function, instead of the user space values, this is for testing
ret = par->fbtftops.write(par, par->txbuf.buf, par->info->var.xres * par->info->var.yres / 8); then display prints full pixels on.
Do you have any answer for this ?

Trying to bring up the SSD1306 OLED display (Monochrome). Need to confirm that my device tree values are proper and the device spi access proper before display anything...
Do you have the function to write the single pixel in OLED display? This function may be in kernel driver or user space applications? This may be in without conversion of RGB or something else.
-Thanks.
