I haven't found any reference to firmware revisions for this chip. There is a mention of "1.5KB OTP to eliminate an external flash". I'm not quite sure how to parse that line item from the brochure. (qca9377-product-brief.pdf)
Does it mean a flashable firmware has been eliminated in lieu of this OTP? (and is "OTP" referring to Open Telecom Platform?)
My underlying question is whether having this chip embedded in my device, do I need to plan to bring firmware updates to it of any kind if and when such firmware updates are made available?
