TS-7970 FPGA Changelog

Check the FPGA rev with:

echo $(($(tshwctl --addr 51 --peek) & 0xf))

Rev	Release date	Changes
0	Jun-17-2015	Initial Release
1	Aug-07-2015	Switched max3100 to use FPGA_IRQ_1 to leave FPGA_IRQ_0 to the silabs.
2	Oct-07-2015	Corrected CTS/RTS polarity on MAX3100 Corrected flipped CPU UART CTS/RTS for bluetooth MAX3100 irq is now FPGA_IRQ_1 instead of FPGA_IRQ_0 so the IRQ is not shared with the silabs. Corrected HD1 SPI bus

Using the u-boot from Oct-07-2015 or later you can reload the FPGA during startup. There is an SRAM reloadable FPGA here. Only the ts7970-fpga*.vme files apply to the TS-7970. For example, to use rev 2 you would download this file and copy it to /boot/ts7970-fpga.vme on your boot device.

During startup you will see u-boot reload this file:
