Hi list, I am trying, with no success so far ,to chain-load the trx-firmware on my c118 with usb-serial-cable.: ------output----- ./osmocon -p /dev/ttyUSB0 -m c123xor -c ../ ../target/firmware/board/compal_e88/trx.compalram.bin ../ ../target/firmware/board/compal_e88/chainload.highram.bin got 2 bytes from modem, data looks like: 04 81 .. got 5 bytes from modem, data looks like: 1b f6 02 00 41 ....A got 1 bytes from modem, data looks like: 01 . got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD opening file: No such file or directory ------------------------------------ I also tried switching highram-compalram: ./osmocon -p /dev/ttyUSB0 -m c123xor -c ../ ../target/firmware/board/compal_e88/trx.highram.bin ../ ../target/firmware/board/compal_e88/chainload.compalram.bin And also ./osmocon -p /dev/ttyUSB0 -m c123xor -c target/firmware/board/compal_e88/trx.compalram.bin target/firmware/board/compal_e88/chainload.highram.bin but got same errors. I used the script in the wiki for building the toolchain prior to building the code. ---------------------------------- Any ideas what might be wrong? Regards erich
