Hello all,
we have been using Cypress RAM for more than 10 years. The component is buffered in the circuit with a battery. For this purpose, the supply voltage and the battery voltage are linked via a simple diode circuit. The chip select line is decoupled via a logic gate, which is also supplied with the buffered voltage. The circuit has been working without any problems for a long time.
The discharge current of the battery is checked during commissioning. This is a few µA.
However, we have recently been experiencing repeated failures with discharged batteries. There are also occasional data losses in the RAM.
Are there any known manufacturer problems with this RAM module that could lead to data loss?
As already mentioned, we have been using the circuit and the RAM module for years without any problems.
Thank you very much.
Hello,
I would like to confirm an issue I have with the SLB9670. My research led me to this thread (https://community.infineon.com/t5/OPTIGA-TPM/IMX8MM-SLB9670-TPM2-Self-test-error/td-p/454162), which seems to suggest everything is normal, but it links to the RPI3. I want to make sure the same applies to the RPI4.
During bootup, I see the following Kernel messages:
[ 9.194573] tpm_tis_spi spi0.1: 2.0 TPM (device-id 0x1B, rev-id 22)
[ 9.197032] tpm tpm0: A TPM error (256) occurred attempting the self test
[ 9.197057] tpm tpm0: starting up the TPM manually
This is slightly annoying, but I can see tpm0
and tpmrm0
in the device section:
user@cm4:~/eltt2 $ ls /dev/tpm*
/dev/tpm0 /dev/tpmrm0
sudo tpm2_gettestresult
status: success
0x00000000: 0xCE 0xFB 0xBB 0x85 0xF2 0x29 0x63 0x1F 0x6A 0xC4 0xDD 0x18 0xC6 0x15 0x25 0x94
0x00000010: 0x48 0x06 0x78 0x92
Finally, sudo tpm2_selftest -f returns 0
Is it safe to assume that my TPM is working correctly despite those messages? It seems like it, but I would appreciate some confirmation.
Thank you!
Show LessHi
I am developing a radar module using BGT60TR13C+ STM32F730.
Since the library provided by Infineon cannot be used directly on the STM32 chip, we are developing a method of writing/reading information by directly accessing the registers provided in the manual.
I would like to ask a question as I have found some problems in proceeding with this method.
1) Is BGT60TR13C operated at default settings when external power is connected?
2) If there is no default setting, which register should be set to operate TX, ADC, etc. of BGT60TR13C?
3) What settings value are needed to drive BGT60TR13C for basic operation?
4) Is there a register full manual for setting and obtaining information?
5) Is there a way to apply/port the code provided by Infineon to the STM32 chip?
Thanks for your time
Regards
Oneman

2、I create a New application ,the procedure as below
the chip change to “CY8C4025LOI-T412” ,the clolk change from 48MHZ to 24 MHZ which was operated as the notes show //-->compile ok
The CY8C4025LOI-T412 project has 4 Buttons(P2.0 、 P2.3、 P2.4、 P2.5) and a I2C(P3.2 P3.3) that is different from the defaut prorammer .yet the progammer is changed //---compile error

Show Less你好,我想请问一下设备的serialNumber如何在外部修改?
在固件代码内部,可以看到有一个描述符是描述这个现象的,
可我现在并不想在内部代码修改此SerialNumber,是否能在外部使用其他的工具进行修改,比如endpoint0对某个地址发送一些固定格式的数据进行修改,或者其他方式修改寄存器等方式呢?
