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

Yes. We actually use this part and a near identical image on another product that uses the Spansion parts primarily. I've seen the same results. Problem with Spansion is they appear to be getting out of the business of smaller QSPI flash parts. It appeared to me that their replacement line started a...

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

I've attached our bin image with custom data that I can program on a unit with IS25LQ, but not IS25LP. To program the units I am programming the IS25LQ080B chips in circuit with the XMOS powered down, but the flash powered up using a total source cheetah spi tool. I then read back the image from the...

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

Ok, 1) removed the IS25LQ016B off our XRHA PCB. 2) programmed the new IS25LP016D flash device -> enabled QSPI mode -> changed the "XMOS" to "MON2" in the 0x80000 offset (custom configuration) region. 3) installed this flash device onto the XRHA PCB. Powered up and the USB device...

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...

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 ...
