Hi, I bought 50pcs STM32L151C8T6A from one Chinese online vendor, which has device marking with QR code.I encountered an issue while using the new version chip, after initial power-on, the overall sleep current of the product is approximately 5uA(STM...
Hi,I'm trying to implement an external loader for the Arduino Giga R1 board with AT25S128A 128Mbit of external flash. After following the guide given in the external loader repo, I'm running into the problem, that I can erase, write & read from the m...
I'm in the middle of attempting to reconfigure the clock tree on my STM32F303K8. The old clock tree looks likeThe new clock tree looks like The old clock tree works fine. The new clock tree always fails on boot; not always in the same address but alw...
Hi Team,I have few questions regarding stm32h7 errata.Errata 2.2.21, Can silicon revision 'V' support a cpu frequency of 480 Mhz ? If yes, why is it showing 'P' for v revision. 2. Can I please ask if there is a fix in the HAL for the below given S...
I'm bringing up a design based off the STM32H573 and I believe I'm having a number of issues that are probably sharing a common thread with bad hardware. I don't usually screw those things up, but I guess I got unlucky this time.1) PC1 when configure...
HI USB-C Input (5–20 V PD) + USB-C Data (USB2.0 D+/D– to STM32H745) + charging phone at same time + Audio data transfer Problem: When I connect the USB-C input supply (PD 5–20 V), the phone only charges and the audio USB port does NOT appear.But when...
Hello everyone,This is my first post on the platform, so please bear with me.I would like to write raw data to an SD card very quickly.After quite a bit of research, I decided to use SDMMC with MDMA, and I want to write directly to the SD card blocks...
I'm trying to port a proprietary code that is designed for another STM32H753 plateform, to a STM32H753-EVAL board.My code remains stuck waiting for HSERDY bit.The setup I am doing looks identical to STM32CubeHW example but I guess I forgot something:...
I want to use N657B0 to drive VD55G0, and the camera side can already enter the Stream state. After I use the function HAL_DCMIPP_CSI_PIPE_Start, I track the variable csi_instance through single-step debugging and find that several bits in its SR1 re...
I have a STM32U595 and I use the RTC in binary mode.If an SSR underflow occurs during Vbat mode, will the SSRUF be set so after power recovery I can manage the interrupt ?
