Well this is not good news (but glad it was not a dumb question). I've got a uSD card in my design as well so what's the best practices plan here when you need a file system? I ironically I got motivated to figure out JTAG so I could debug my attempt to get SPIFFS working. I'm thinking the best I ca...

I see info in the tech_ref that suggests JTAG can be remapped with Direct I/O via IO_MUX. Section 4.4.2 is a bit thin but I'm not seeing alternate pads that can accept MT* functions.

Got a TIAO USB JTAG V2 board (http://www.diygadget.com/tiao-usb-multi-protocol-adapter-lite-jtag-spi-i2c-serial.html) running using the Espressif's JTAG Debugging doc under x86_64 Linux. Here's a few notes: Install the linux FTDI driver http://www.ftdichip.com/Drivers/D2XX.htm Do as described in Rea...

ack! well that's embarrassing..... I just copied my esp8266 pin mapping from last years board and didn't scan the table for new conflicts.

Thanks for the help.

Hey I first gotta say your book has been a fantastic resource! GPS is on the default GPIO's 9&10 for UART1. Didn't have a breadboard for the GPS chip so didn't see this until I soldered up a pcb. Next rev I'll put the GPS on uart2 and for now I'll cut and solder traces unless there is some software ...

I've got a free running GPS on UART1 that if the darn thing gets a fix and starts sending data it corrupts flash downloads as it appears the data gets merges with the real data being sent on UART0 (MD5 match errors etc). Obvious solution is to move the GPS to UART2 or but wondering is there a way to...
