Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

Could it be that the Read JEDEC ID command is not executed by the OTP code? We know that the OTP code will (successfully) read a large chunk of data from the flash. Perhaps that code is executed and it tries to read the remainder of the data from the flash. Consider that after a period of inactivity...

Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

There are too many variables at play and need to streamline the permutations. That was my thinking as well. By using "non-custom" hardware and software (i.e. an XMOS reference design), the focus is squarely on the SPI flash memory since we know that the hardware works and the SPI flash da...

Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

There is a "XCORE audio configuration utility" that can generate a flash image including the configuration data.
I tried to upload a binary image file with no success.



Regards,

Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

To summarize, your firmware with your customized configuration, if applied to the original ISSI device (ISSI LQ 080) will boot fine with the XMOS CPU? Then the same firmware image, when programmed into a same density part (as above) but this part is the new version (ISSI LP 080) from ISSI, will onl...

Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

Thanks for the quick response! We have used the same XMOS silicon and board with both a 'working', and 'non-working' part. Using the original Spansion FL116K, or ISSI LQ080 parts everything works as advertised. When we use anything else, so far, the results are either: 1) Doesn't load at all. 2) Lo...

Re: XHRA-2HPA-TQ64 doesn't load unique configuration data at 0x80000 addr

I have a design I adopted that uses an XMOS XHRA-2HPA-TQ64. It historically has used ISSI and Spansion SPI flash parts as listed in the datasheet and on these forums. Specifically, IS25 LQ 080. ISSI now show this part as end of life and its replacement part is supposed to be IS25 LP 080. When I use...
