mlaz commented on issue #46: Zephyr support URL: https://github.com/apache/mynewt-mcumgr/pull/46#issuecomment-564217554 > Unfortunately shell transport has regression - I was able to finish upload only one time in few trial while with zephyr master version it works just perfectly. @de-nordic can you help to find regression reason. @nvlsianpu I have been trying to reproduce that bug and I can upload every time via serial, both erasing progressively and doing a single step erase. I am using a serial adapter, connected to the serial pins on an nRF52dk. Once I try using the J-Link serial line the behaviour gets unstable using most of the mcumgr commands. From this output snippet you may see that probably the shell running on the uart is causing the problem, I don't think this is fixable on the mcumgr side. ``` DEBU[2019-12-10 17:44:44.861] Tx serial 00000000 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 |AAAAAAAAAAAAAAAA| 00000010 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 |AAAAAAAAAAAAAAAA| 00000020 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 |AAAAAAAAAAAAAAAA| 00000030 41 47 56 70 62 57 46 6e 5a 51 42 6a 62 47 56 75 |AGVpbWFnZQBjbGVu| 00000040 47 53 6c 67 59 32 39 6d 5a 67 42 6a 63 32 68 68 |GSlgY29mZgBjc2hh| 00000050 57 43 43 6d 35 66 65 71 50 41 58 6a 4e 71 38 79 |WCCm5feqPAXjNq8y| 00000060 4a 44 64 58 7a 72 69 6d 35 66 64 6b 37 79 71 4a |JDdXzrim5fdk7yqJ| 00000070 32 4e 46 64 69 42 57 4f 49 38 2f 48 |2NFdiBWOI8/H| DEBU[2019-12-10 17:44:44.861] Tx serial 00000000 0a |.| DEBU[2019-12-10 17:44:44.867] Rx serial: 00000000 1b 5b 6d 1b 5b 31 3b 33 32 6d 75 61 72 74 3a 7e |.[m.[1;32muart:~| 00000010 24 20 1b 5b 6d 55 53 42 53 |$ .[mUSBS| DEBU[2019-12-10 17:44:44.87] Rx serial: 00000000 1b 5b 31 3b 33 31 6d 55 53 42 53 3a 20 63 6f 6d |.[1;31mUSBS: com| 00000010 6d 61 6e 64 20 6e 6f 74 20 66 6f 75 6e 64 |mand not found| DEBU[2019-12-10 17:44:44.873] Rx serial: ```
