Subject: [PATCH v3 0/1] misc: st32fwu: Add stm32 upgrade protocol handling
Date: Tue, 14 Oct 2014 16:37:44 +0200 [thread overview]
Message-ID: <1413297465-11039-1-git-send-email-k.wrona@samsung.com> (raw)
Hello,
This patch is needed by the sensorhub driver which uses STM32F4xx and Jonathan
suggested to factor out these sources (mentioned in:
[RFC/PATCH 2/6] misc: sensorhub: Add sensorhub).
I feel a bit ashamed because I know a bit STM32F4 controllers but I did not
realize that it is generic ST protocol. It helped us a lot because this
code really needed some refactoring.
So this patch contains SPI protocol used in the STM32 bootloader and is based
on AN4286. Generally it can be used to implement handling of other interfaces
like UART or I2C because the flow is quite similar and maybe adding proper
hw access callbacks will do all work.
It supports:
- get info frame
- get version
- firmware write (write, read, write address, erase)
>From v2:
some typos fixes
kfree to devm_kfree in error handling
...
generally things advised by Antonio Borneo for v2
TODO (I will not have had time to touch it for few weeks):
erase command with sector mode
command checking and disabling unimplemented ones
Also some Antonio opinion is needed if we are able (or want) to use the same
stm32_core layer for this.
