Hi, I tried to implement the mtb-littlefs in my xmc7100D board with few modification to mq serial-read/write program: But I am encountering an error: could you tell me why I am unable to do "
lfs_file_read(lfs, &file, &boot_count, sizeof(boot_count));
"
My COM Port:
in my lfs.c:
lfs_ssize_t lfs_file_read(lfs_t *lfs, lfs_file_t *file,
void *buffer, lfs_size_t size) {
int err = LFS_LOCK(lfs->cfg);
if (err) {
return err;
}
LFS_TRACE("lfs_file_read(%p, %p, %p, %"PRIu32")",
(void*)lfs, (void*)file, buffer, size);
printf("lfs_file_read(%p, %p, %p, %"PRIu32")",
(void*)lfs, (void*)file, buffer, size);
LFS_ASSERT(lfs_mlist_isopen(lfs->mlist, (struct lfs_mlist*)file));
lfs_ssize_t res = lfs_file_rawread(lfs, file, buffer, size);
LFS_TRACE("lfs_file_read -> %"PRId32, res);
LFS_UNLOCK(lfs->cfg);
return res;
}
How do I solve the LS_ASSERT function from failing?
Also how do I verify little_fs is not mounted on the internal flash but on the inbuild external flash memory.
Best,

您好,我在使用xmc4800,ethercat。这个示例代码ETHCAT_SSC_AUT_BASE_XMC48里添加PMSM_FOC组件,报了两个错误,我在单独使用PMSM_FOC这个工程正常编译运行。但在ETHCAT_SSC_AUT_BASE_XMC48就会出现这两个问题,请看附件图
多次尝试无法解决,请帮看一下。感谢!!!
Show LessHi
I want to know sleep current of TLE9853QX & also it auto wake when LIN signal is available. My customer is using in Flush door handle.
I have seen multiple sleep mode specs available in datasheet but not able to understand actual avg sleep mode current required.

TL9183Q MLCC Chip Capacitor for Charge Pump CB 4.7uF It is prone to whistling, and replacing it with a larger or smaller capacitor value does not improve it much.
Any good solutions?
Show LessHello all,
I am very tired to work with FOC using imc101t-f048, In this FOC method i cannot achieve 3000rpm in 2sec(This is already discussed in this thread (https://community.infineon.com/t5/Motor-Control-ICs/FOC-vs-Trapesoidal/m-p/711550#M3771)) , so i decided to work in Trapezoidal commutation. Kindly clarify IMC101t-f048 microcontroller does support trapezoidal commutation. If support which software is used for trapezoidal like MCE wizard for FOC?

Hello everyone, my board needs to use a SmartPIM1 series IGBT module: FP35R12U1T4, according to the SmartPIM1 assembly instructions AN2009_09, PCB boards have a layer of tin after the metalization of the aperture, I would like to ask this layer of tin is plated with the surface treatment using the sinking tin process? It seems that most PCB manufacturers nowadays are spraying tin, and there seems to be only copper on the inside of the holes, will this affect the assembly?
Another problem is that according to the assembly instructions the board needs to be drilled between 1.12mm ~ 1.15mm, I can find the best precision factory crimp hole hole diameter tolerance is also ± 0.05mm, it seems not quite able to meet the error requirements. I would like to ask you to play this kind of board to find what manufacturers to meet the requirements?
Show LessHii,
I'm using CYTVII-C-2D-6M-327-SET evaluation kit for my project. I require information's about pinout details exposed out in dev kit and its schematic diagram .
I couldn't get those documents. could you support on this ?
Thanks.
