![]() ![]() Mon2, this is your reply on thread "How can I program an XHRA 2HPA" Which model of programmer do you own?Īfter further reading I found a reply on another thread that may answer a couple of my questions. This very important else the XMOS CPU will not be able to boot the firmware. You need to check the USB flash programmer you own for the details on how to ENABLE the QSPI bit for your brand and model of the flash device. After this initial "booting via your pre-programmed flash" - only then you can do field upgrades to the XMOS supplied IP. It will be wise to read a few of the posts to get a feel of the task but the summary, once again is:Ī) this XMOS audio specific processor contains factory OTP code which demands that the external flash device you have applied is enabled to operate in QSPI mode (this is a single non-volatile bit) inside the device.ī) the firmware you need to inject into the flash device is also posted but can email you via a private email.Ĭ) the OTP code inside the CPU CANNOT program your external flash device so you must do this with external tools and then solder into place. This topic has been covered many times but openly the details are scattered across this forum. ![]()
