[jira] [Updated] (MYNEWT-787) serial boot loader - newtmgr buffer
overruns
[ https://issues.apache.org/jira/browse/MYNEWT-787?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Christopher Collins updated MYNEWT-787:
---------------------------------------
Description:
(Pull request: https://github.com/apache/incubator-mynewt-core/pull/340)
The serial boot loader fails to process some newtmgr commands:
1. The image list response is too large for the outgoing buffer.
2. The "new" newtmgr sends large image chunks in its image upload requests. These chunks are too large for the serial boot loader's input buffer.
The fixes are as follows:
1. Increase the outgoing buffer size from 48 to 128.
2. Increase the incoming buffer size from 128 to 512.
3. Return an error rather than overrun the output buffer.
