Greetings all, long time lurker/first time poster here.
I'm attempting to make some custom Teensy 4.x boards, and I'm encountering the 3 flashes for "Flash Chip Error, Missing or Incorrect ID". In my design I'm using the W25Q64JVSSIM (SOIC-8 Package), and in each of my prototype boards I'm seeing the same error. However, I de-soldered a W25Q64JVXGIM Flash Chip off of a Teensy4.1 (XSON-8 package), and was able to solder wire leads from the chip to the pads on the PCB...and interestingly everything works perfectly.
So I'm wondering, does a virgin Flash Chip require some form of initialization in order to wake up and reply to the JEDEC ID query from the bootloader, or sync with the chip?
I've verified the markings on the flash chips are indeed correct versions ending with "M", the traces and contacts are solid, and the response/error is the same regardless to pressing the program button once or doing the reset via ~15second hold > release.
Overview of custom board:
- IMXRT1062DVL6B (10mmx10mm)
- MKL02 bootloader from PJRC (Big THANK YOU for creating and selling these!)
- W25Q64JVSSIM SPI Flash Chip
- Schematic for power supply, bootloader, flash chip, crystals, etc is pretty much identical to recommended specs
Incase it might be of use, the following is the verbose log when connecting to the original W25Q64JVSSIM flash chips, and pressing the Program button.
Then here's the verbose log when connecting to another prototype pcb, which is fully working now that I've replaced the W25Q64JVSSIM with the W25Q64JVXGIM chip that I'd taken off of a T4.1:Code:05:46:57.319 (loader): Teensy Loader 1.57, begin program 05:46:57.355 (loader): Listening for remote control on port 3149 05:46:57.356 (loader): initialized, showing main window 05:47:06.513 (loader): Verbose Info event 05:47:10.190 (loader): HID/macos: attach callback 05:47:10.356 (loader): HID/macos: number of devices found = 1 05:47:10.360 (loader): HID/macos: vid=1FC9, pid=0135, page=FF00, usage=0001, ver=1.01 05:47:10.365 (loader): Device came online, code_size = 100 05:47:10.367 (loader): Board is: NXP IMXRT1062 ROM 05:47:10.369 (loader): begin operation 05:47:10.371 (loader): set background IMG_ONLINE 05:47:10.389 (loader): HAB open mode, bootcfg=80018 05:47:10.393 (loader): Opps, NXP ROM in open mode, but we do not yet have code for this case :( 05:47:10.395 (loader): start ignoring 7ff0a8316d70 05:47:10.396 (loader): HID/macos: IOHIDDeviceClose called! 05:47:10.397 (loader): end operation, total time = 0.027 seconds 05:47:10.399 (loader): redraw timer set, image 79 to show for 3000 ms 05:47:10.606 (loader): HID/macos: number of devices found = 1 05:47:10.611 (loader): HID/macos: none of the devices had known usage 05:47:13.400 (loader): redraw, image 9 05:47:15.937 (ports 1): HID remove callback 05:47:15.937 (loader): HID/macos: detach callback: is NOT currently open device 05:47:15.937 (ports 1): USB device remove callback 05:47:15.937 (ports 1): remove, loc=14100000 05:47:15.941 (loader): stop ignoring 7ff0a8316d70 05:47:16.332 (ports 1): USB device add callback 05:47:16.333 (loader): remote connection 3 opened 05:47:16.405 (loader): HID/macos: attach callback 05:47:16.606 (loader): Device came online, code_size = 100 05:47:16.610 (loader): Board is: NXP IMXRT1062 ROM 05:47:16.613 (loader): begin operation 05:47:16.616 (loader): set background IMG_ONLINE 05:47:16.629 (loader): HAB open mode, bootcfg=80018 05:47:16.633 (loader): Opps, NXP ROM in open mode, but we do not yet have code for this case :( 05:47:16.635 (loader): start ignoring 7ff0a812d070 05:47:16.637 (loader): HID/macos: IOHIDDeviceClose called! 05:47:16.638 (loader): end operation, total time = 0.023 seconds 05:47:16.640 (loader): redraw timer set, image 79 to show for 3000 ms 05:47:16.856 (loader): HID/macos: number of devices found = 1 05:47:16.858 (loader): HID/macos: none of the devices had known usage 05:47:19.643 (loader): redraw, image 9

Any advice would be appreciated!
