Hi,

I did notice just now there is some TRX support for USB broadcom devices ?


TRX is a format that is also used for partitioning flash devices, so there is probably some room for making a common header:

./Documentation/devicetree/bindings/mtd/partitions/brcm,trx.txt/drivers/mtd/parsers/parser_trx.c

Is that format somehow standardized ? I recall it was used on some OpenWRT routers ?

It seems the TRXSE (whatever it is) is used more like a carrier for the firmware blob (chunks?) which are pushed into SRAM (?) of the CYW55572 device.
