[PATCH 0/4] Fixes for gta0x targets

Hi all, I've been trying to join the party with my OpenMoko GTA02, and I found that a few tweaks were required. Patch 1/4 was required to get the romloader to start, otherwise osmocon would only receive an occasional '\x00' character instead of the ident_cmd. It works perfectly with the beacon interval reduced to 13 mS, but I've made it configurable just in case other targets don't like it. Patches 2/4 and 3/4 are bugfixes for the calypso uart code. The LCR register ended up being clobbered, and this rendered the uart on my board silent. Finally, I'm using the GTA02 AP as the "host", communicating via the internal ttySAC0 UART. Patch 4/4 allowed me to cross-compile osmocon & friends on my x86 box with the AP ARM as the target. Now I can run, ./osmocon -m romload -p /dev/ttySAC0 -i 13 -d tr firmware/layer1.highram.bin while toggling power via, echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on and get: OSMOCOM Layer 1 (revision osmocon_v0.0.0-696-ge801cee-modified) ====================================================================== Device ID code: 0xb496 Device Version code: 0x0000 ARM ID code: 0xfff3 cDSP ID code: 0x0128 Die ID code: e4942219e4949b52 ====================================================================== REG_DPLL=0x2413 CNTL_ARM_CLK=0xf0a1 CNTL_CLK=0xff91 CNTL_RST=0xfff3 CNTL_ARM_DIV=0xfff9 ====================================================================== Cheers, Alex Alex Badea (4): osmocon: make beacon interval configurable via cmdline target uart: fix preservation of LCR target uart: remove REG_OFFS() macro side-effect toplevel Makefile: accept arguments for host ./configure calls src/Makefile | 8 ++++---- src/host/osmocon/osmocon.c | 26 ++++++++++++++++---------- src/target/firmware/calypso/uart.c | 10 +++++----- 3 files changed, 25 insertions(+), 19 deletions(-)
