NXPTM M522XX, KINETIS and i.MX RT / Kinetis MK66, how overclock to 240Mhz
« on: October 12, 2019, 06:37:48 AM »

Hello Mark.

I want to apply overclock to a Kinetis MK66, to run at 240Mhz, I know it is possible because with the Teensy 3.6 I can apply an overclock at 192, 216 and 240Mhz, using the same microcontroller.
 
But I prefer to work with MCUXpresso, the problem is that I don't know how to configure it here, I have tried several combinations of the PLL but it always gives me error. The only sure  is that the maximum frequency of the VCO is 360Mhz according with the datasheet.

Can you help me to apply overclock at 240Mhz with a Kinetis MK66 using MCUXpresso ??

Regards

STTM STM32 and STR91XF / Compile for STM32F746 fail

Hello Mark.

I have run STM32F746 version with Coocox, but when I compile, fail with one error.
How can I solve please ?

Attached capture screen with the error.
\Applications\uTaskerV1.4/debug.c:2778: undefined reference to `fnUpTime'
collect2.exe: error: ld returned 1 exit status


How can I configure for bootloader with SD card and STM32F746 ?


Best Regards

STTM STM32 and STR91XF / STM32F405/407VGT6 Bootloader Configuration
« on: October 02, 2017, 10:43:00 PM »

Hello.
After the success with uTasker SD Bootloader for Kinetis, I tried to do the same for STM32, I have some questions please:
 
1.- Not available to use the project in Eclipse ?, I have opened it with Coocox, but I prefer Eclipse if possible.

2.- I want to use for an STM32F405 or STM32F407 with bootloader from SD card by SDIO. It's correct if I choose ST_MB997A_DISCOVERY ?, The SD will not be for SPI, but for SDIO, I'm not sure how select it.

3.- What is the parameter I must configure to enable bootloader from SD card ?. need force boot and not retain loader to enter in boot mode without switches and SD socket with no sd card switch detect.

4.- In config.h I have enable  SDCARD_SUPPORT, but when I go to app_hw_stm32.h  the  "#if defined SDCARD_SUPPORT" is dissabled. What may be the problem ?.

5.- With this bootloader for STM32, the user application must compile also to start in 0x8000 or what is the correct start address for STM32 ?.

6.- There is no "#define DELETE_SDCARD_FILE_AFTER_UPDATE" to allow delete firmware automatically after load ?.
 
Best regards.
