a806aedb13 STM32F33: Support for COMP character driver 2017-03-25 16:57:43 +01:00
Alexander Oryshchenko
61ff3c6b84 I needed to use DS3231, I remember that in past it worked ok, but now for stm32f4xx is used another driver (chip specific, stm32f40xxx_i2c.c) and DS3231 driver doesn't work. After investigating a problem I found that I2C driver (isr routine) has a few places there it sends stop bit even if not all messages are managed. So, e.g., removing stm32_i2c_sendstop (#1744) and adding stm32_i2c_sendstart after data reading helps to make DS3231 working. Verified by David Sidrane. 2017-03-24 06:44:33 -06:00

b9b4f184a7 stm32: Add workaround for flash data cache corruption on read-while-write
This is a know hardware issue on some STM32 see the errata of your model
and if you make use of both memory banks you should enable it.

09f70c462d stm32: Make up_progmem thread safe
Writing to a flash sector while starting the erase of other sector
have a undefined behavior so lets add a semaphore and syncronize
access to Flash registers.

But for the semaphore to work it needs to be initialized so each
board needs call stm32_flash_initialize() on initialization, so
to avoid runtime problems it is only using semaphore and making
it thread safe if initialized, after all boards starts to call
stm32_flash_initialize() we can remove the boolean and the check.

80f56e75f9 stm32: Fix erase sector number for microcontrolers with more than 11 sectors
Erase a sector from the second bank cause the bit 4 of SNB being set
but never unsed, so trying to erase a sector from the first bank
was acually eraseing a sector from the second bank.

9b11187b2a STM32 OTG HS: A little research reveals that only the F2 RCC initialization set the OTGHSULPIEN bit and Photon is the only F2 board configuration that uses OTG . Therefore, we can simplify the conditional logic of the last PR. Negative logic was used (#ifndef BOARD_DISABLE_USBOTG_HSULPI) to prevent bad settings in other configurations. But give these facts, the preferred positive logic now makes more sense (#ifdef BOARD_ENABLE_USBOTG_HSULPI). 2017-03-11 18:00:38 -06:00

acaebb361b STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to similar STM32 I2C drivers.
Save elapsed time before handling I2C in stm32_i2c_sem_waitstop()
   This patch follows the same logic as in previous fix to
   stm32_i2c_sem_waitdone().
   It is possible that a context switch occurs after I2C registers are read
   but before elapsed time is saved in stm32_i2c_sem_waitstop(). It is then
   possible that the registers were read only once with "elapsed time"
   equal 0. When scheduler resumes this thread it is quite possible that
   now "elapsed time" will be well above timeout threshold. In that case
   the function returns and reports a timeout, even though the registers
   were not read "recently".
   Fix this by inverting the order of operations in the loop - save elapsed
   time before reading registers. This way a context switch anywhere in the
   loop will not cause an erroneous "timeout" error.

a3b4475474 STM32, STM32 F7, and STM32 L4: Back out part of 3331e9c49a. Returning immediately int he case of a NAK makes the Mass Storage Class driver unreliable. The retry/timeout logic is necessary. This implementation tries to implement a compromise: If a NAK is received after some data is received, then the partial data received is returned as with 3331e9c49a. If if a NAK is received with no data, then no longer returns the NAK error immediately but retries until data is received or a timeout occurs. Initial testing indicates that this fixes the issues the MSC. However, I hae concerns that if multiple sectors are read in one transfer, there could be NAKs between sectors as well and, in that case, then change will still cause failures. 2017-03-09 13:49:25 -06:00
