( https://gerrit.osmocom.org/c/simtrace2/+/26998 ) Change subject: fw/qmod: enable modem RESET by default at boot ...................................................................... fw/qmod: enable modem RESET by default at boot When the uC firmware starts, assert the (high-active) _RESET GPIOs, which will cause the transistors to drive the mPCIe slot !PERST low. There is of course a short instance of time between the uC reset until it executes wwan_perst_init(). To avoid this, a hardware pull-up would have to be re-worked onto the _RESET[1..4] signals on the PCBA Change-Id: I8742fefa4bf02e728e34d5d8cbc0fda771e78ffb --- M firmware/libboard/qmod/include/board.h 1 file changed, 2 insertions(+), 2 deletions(-) git pull ssh://gerrit.osmocom.org:29418/simtrace2 refs/changes/98/26998/1 diff --git a/firmware/libboard/qmod/include/board.h b/firmware/libboard/qmod/include/board.h index 7ea5bd7..56d0d21 100644 --- a/firmware/libboard/qmod/include/board.h +++ b/firmware/libboard/qmod/include/board.h @@ -89,8 +89,8 @@ #define PINS_WWAN_IN { PIN_WWAN1, PIN_WWAN2 } /* outputs controlling RESET input of modems */ -#define PIN_PERST1 {PIO_PA25, PIOA, ID_PIOA, PIO_OUTPUT_0, PIO_PULLUP} -#define PIN_PERST2 {PIO_PA26, PIOA, ID_PIOA, PIO_OUTPUT_0, PIO_PULLUP} +#define PIN_PERST1 {PIO_PA25, PIOA, ID_PIOA, PIO_OUTPUT_1, PIO_PULLUP} +#define PIN_PERST2 {PIO_PA26, PIOA, ID_PIOA, PIO_OUTPUT_1, PIO_PULLUP} #define PINS_PERST { PIN_PERST1, PIN_PERST2 } #define PIN_VERSION_DET {PIO_PA19, PIOA, ID_PIOA, PIO_PERIPH_D, PIO_DEFAULT} -- To view, visit https://gerrit.osmocom.org/c/simtrace2/+/26998 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: simtrace2 Gerrit-Branch: master Gerrit-Change-Id: I8742fefa4bf02e728e34d5d8cbc0fda771e78ffb Gerrit-Change-Number: 26998 Gerrit-PatchSet: 1 Gerrit-Owner: laforge <laforge(a)osmocom.org> Gerrit-MessageType: newchange
