I did this for a short time and very quickly removed it. The case is that the i.MX21 has 6 GPIO blocks with 32 bits each. However, not all 192 pins are actually GPIOs, but most of them have very normal functions, e.g. LCD output. So many of those pins are driven by internal hardware blocks, e.g. PCMCIA interface, LCD controller, CSPI, I2C, USB host etc. But even when a pin is used not as a GPIO, but by the controller, the output/input of the physical pin is reflected in the GPIO state- and level registers. You can imagine how often this changes for, say, the LCD panel line- and frame-clock signals. So an "watch GPIOS" command emits almost only uninteresting stuff and I thougth it much wiser to individually add those registers to the watch that are really of interest. _______________________________________________ Haret mailing list [email protected] https://handhelds.org/mailman/listinfo/haret
