Nor Flash Forum Discussions

Please tell me the thermal resistance θJc, θja of 29AL008J70TFI010.
I want to know where to look in the data sheet

Stm32h743 is connected via FMC s29gl064s，and cubeide configed. As shown below:

RCC configured as below：

Read flash ID：

sts = HAL_NOR_Read_ID(&hnor1, &id);
printf("sts1 = %d\n", sts);

printf("nor_id = %04x %04x %04x %04x\n",
id.Manufacturer_Code,
id.Device_Code1,
id.Device_Code2,
id.Device_Code3);
HAL_Delay(1);

Return：nor_id = 0001 227e 2213 2201

Then ReturnToReadMode:
sts = HAL_NOR_ReturnToReadMode(&hnor1);
printf("stsreadmode2 = %d\n", sts);
HAL_Delay(1);

EraseChip：

sts = HAL_NOR_Erase_Block(&hnor1, 0, 0x60000000);
printf("sts_erase_block = %d\n", sts);

do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);

Return status look like correct.

Write operation：

uint16_t txbuf[1024] = {0}, rxbuf[1024] = {0};
#if 1
for (i = 0; i < 1024; i++) {
txbuf[i] = 0x5a;
}
#endif
sts = HAL_NOR_ProgramBuffer(&hnor1, 0, txbuf, 256);
printf("sts_write_buf = %d\n", sts);

do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);

Return status look like correct.

Read operation：

sts = HAL_NOR_ReadBuffer(&hnor1, 0, rxbuf, 256);
printf("sts_read_buf = %d\n", sts);
#if 1
do {
sts = HAL_NOR_GetStatus(&hnor1, 0x60000000, 500);
printf("HAL_NOR_GetStatus1 = %d\n", sts);
} while(sts);
#endif
for (i = 0; i < 256; i++) {
if (!(i % 8)) {
printf("\n");
}
printf("%04X ", rxbuf[i]);
}
printf("\n");

Return resaults as below：

 According to your tips, I added the HAL_NOR_ReturnToReadMode function.

But the result is still incorrect! Please help me look again. What's the problem。

Thanks.

Hello, good morning.
I got some doubts regarding the S70FL01GSAGMFI010 flash memory
As it works with SPI, I would like to know if it is possible to use the same protocol usually used with SD cards (SPI+FAT file system).
Thanks in advance, Luis Felipe.

We bought the part  S25FL512SAGMFIR10, the date code is 19+ , but the marking is different from what data sheet said.

Is there anyone who can help to answer?  Thank you!

Hi Bushra

I registered for the Semper Access Program (AP) on January 11, but still do not have full access to the datasheets for S25HL512TDPNHI010.

In the instructions to "Join the Semper™ Access Program for full access to SEMPER NOR Flash design files" in step 3 it is mentioned that "within 24-48 hours, you will receive an invitation message in your Cypress community messages inbox"

The "48 hours" have passed, but I did not receive an invitation in my "Cypress community messages inbox".

I tried the link you provided this morning "https://community.infineon.com/t5/Semper-Flash-Access-Program/Datasheet-Semper-Flash-with-Quad-SPI/ta-p/260789" but I still do not have access.

Can you please help?

Many thanks

Hello,

I have replaced my Winbond flash w25q256jv with S25FL256SAGNFI010. What are the major electrical points I have to take care of while designing the schematic? is there any particular thing I have to consider while making a design or while writing up the code?

In the initial stage, both the flash seems perfect while compared with each other as far as functional working is a concern.

would like to have your say on this at the earliest as we are in the final stage of our product.

Can you please share with us the sample code for this flash having serial spi flash configuration, erase, read and write operation?

Any help will be grateful. Thanks in advance.

Regards,

Shivam Shah

Sir,

  Do we have sample code to let customer know how to exit safe-mode of Semper flash ?

  Thanks.

The FLASH detailed model is S29GL064S70TFI070.  

Is the flash ID correct???

Read flash ID：

sts = HAL_NOR_Read_ID(&hnor1, &id);
printf("sts1 = %d\n", sts);

printf("nor_id = %04x %04x %04x %04x\n",
id.Manufacturer_Code,
id.Device_Code1,
id.Device_Code2,
id.Device_Code3);
HAL_Delay(1);

Return：nor_id = 0001 227e 2213 2201

Thank you very much.
