It would be really interesting to know why Keil omitted driver for SPI4 in their BSP software pack for STM32F4 family - SPI1, SPI2, SPI3 and SPI5 are supported, but SPI4 (and SPI6, for that matter) are not... Not to mention wrong DMA channel assignments for SPI2. I mean, it's not a problem to fix such things, but then new release comes out and you can't just upgrade, since bugs might not be fixed and you have to do it all over again. Pretty lousy work...
this issue is kind of moot due to the afct that manufacturers updts are notoriasly slow getting into the Keil directories.
when using device specifi code ALWAYS get it from the manufacturers website

PS not a big blame to Keil, keeping up with every manufactutrers upgrades (often no message "xx is updated" is sent) would be a herculean task
I am not complaining about missing drivers - I am complaining about poorly written ones. If they decided to release a driver, somebody should at least check for formal errors...
Well, "It would be really interesting to know why Keil omitted driver for SPI4..." certainly sounds like a complaint about a missing driver to me!
Let's make things clear - in RTE there's a single SPI driver file that contains instances for SPI1, SPI2, SPI3 and SPI5. Even if you consider it as a separate driver for each SPI interface, there are still bugs that make it clear nobody tested it for real at all - like wrongly assigned DMA channels, for example... Anyway - over and out.
still bugs that make it clear nobody tested it for real at all - like wrongly assigned DMA channels, for example did you get it from Keil or ST?
... whose name is in the copyright notice?
Yes, and isn't a great deal of software coded without direct access to hardware, in all possible permutations. Sometimes you're just given a specification and told to make it happen.
How many halfwits have we seen here complaining that something compiles and links without error, but then fails to actually work, as if the syntax checker can diagnose programming errors.
Submit a bug report to support, and move along. Better yet, fix the problems as you see them, and submit a complete patch with your report.
